What do you mean this whole time we could have been the Jamgrass Situation!?

Ever since the earliest days of BGS we’ve been posting about bluegrass, hosting bluegrass shows, and shooting bluegrass Sitch Sessions. Our often-viral performance videos have been the bread and butter of the brand. Along the way, with our borderless and wide open “rootsy” purview, quite a bit of bluegrass “coloring outside the lines” has been celebrated on our site and jamgrass has permeated everything we’ve done. As the years went on, the influence of bluegrass’s current biggest phenomenon became more and more apparent on the site.

You can see this fact – obviously! – throughout our archive of Sitch Sessions. It’s quite the collection of first-rate jamgrass. Over more than 15 years we’ve had dozens of Sitch Sessions and YouTube videos feature some of the best and most beloved jamgrass acts around. One of our very first viral sensations was a now-retired clip of Billy Strings himself. But so many more have featured on our site and channels: Yonder Mountain String Band, The Lil Smokies, Elephant Revival, Front Country, Punch Brothers, Fruition, Greensky Bluegrass, Town Mountain, Mountain Grass Unit, Lindsay Lou, AJ Lee & Blue Summit, the Travelin’ McCourys, the Hillbenders – and many, many more.

From rooftops in downtown L.A. to Falkenberg, Sweden, to DelFest in Cumberland, Maryland, to the powdery slopes above Lake Tahoe to Telluride, Colorado, and back again. Across the trajectory of BGS over time, jamgrass has been an indelible through line of the work we do and the content we create. And we wouldn’t have it any other way!

To celebrate Jamgrass in July, enjoy exploring these 30 jamgrass Sitch Sessions. And dive into the archive here and here to see even more! Just for today, just for this month – let’s be the Jamgrass Situation.

“Take a Chance on Me” – Yonder Mountain String Band

We’ve gotten the chance to collaborate with Yonder Mountain String Band quite a bit over the years, but this Sitch Session has always been a highlight of our content together. YMSB have been carrying the jamgrass banner for a long time; they are stalwarts of the subgenre, for sure!

“Miss Marie” – The Lil Smokies

But why did the Lil Smokies have to retire!? We miss them so much already. If you miss them as much as we do, check out our final interview with the group posted in April 2025 on the heels of their excellent last album, Break Of The Tide.

“Cedarwood Pines” – The Brothers Comatose

Across the decades and generations you can always count on the Bay Area to produce excellent jamgrass. The Brothers Comatose certainly fit that descriptor! “Cedarwood Pines,” shot on a picturesque DTLA rooftop in 2017, features a classic lineup of the group and (gasp!) electric guitar!? (That’s how you know it’s jamgrass.)

“If Something Breaks” – Front Country

Speaking of Bay Area jamgrass – and bands we wish hadn’t retired! Front Country may be no more, but we’re glad we have our Sitch Session memories. And of course, the members of FroCo have gone on to do even more excellent things in roots music. For instance, have you heard BERTHA? Now there’s some jamgrass, too.

“Wasting Time” – Nathaniel Rateliff & the Night Sweats

Sometimes a band that isn’t a jamgrass band is a jamgrass band, you know what we mean? Now, are Nathaniel Rateliff & the Night Sweats always a jamgrass band? Perhaps no. But here, in our Sitch Session, or in many of their live, all-skate jam or festival or collaboration set contexts? Could be jamgrass… It’s always in the ear of the beholder, after all.

“Winter to Pry” – The Deer

That time we shot sessions at Old Settler’s in Austin, Texas, was one of the best. Such a great range of acts, sounds, and styles. The Deer turned out a perennial favorite Sitch Session for us, which we returned to time and time again as winter would roll in. The outdoor Austin shoot and the Deer’s offering of the song would always warm us up.

“All Day All Night” – River Whyless

If you miss River Whyless, worry not, this band hasn’t retired, they’ve just slowed down a bit and re-intentionalized their performing and touring rhythms. We once featured the group on our stage at Bonnaroo and while their sound always defied perfect categorization, here on “All Day All Night” and on festival stages – and elsewhere, to be sure – they often fit the jamgrass bill perfectly.

“Hey Boys” – The HillBenders

Recently the HillBenders have slightly shuffled their lineup, but the Missouri-based band are still one of the most party-ready groups on the bluegrass and jamgrass scenes. Their work with Keller Williams and Tommy: A Bluegrass Opry are the jammiest of their offerings, but the threads and vibes of jams and jamgrass are woven throughout their work.

“Home In Your Heart” – Elephant Revival

One of our coolest Sitch Session locations ever! Out in the desert in Pioneertown, California, with Elephant Revival. This has always been such a memorable one. Here’s another group we greatly miss.

“Dance You Hippy Dance” – Tim O’Brien

What do you call a forefather who’s also a currentfather? That’s what Tim O’Brien is to jamgrass, a foundational figure who’s also active in the music and in moving it forward. And what would jamgrass be without dancing hippies? Nothing! It would be nothing!

“Burn Them” – Greensky Bluegrass

One of our most-viewed Sitch Sessions of all time, and it’s no wonder. Greensky Bluegrass epitomize the ethos of jamgrass – community, longevity, collaboration, and of course, jams. Every time we collaborated with Mason Jar Music, who produced this session, the results would be stellar. With 1.5 million views and counting… jamgrass is where it’s at.

“Death Comes Knockin’” – Fruition

When bands and performers would route through Los Angeles, we often jumped at the chance to link up and capture some content. In 2016, we met up with Fruition in Echo Park to shoot “Death Comes Knockin’” a rocking, macabre song that’s as old-timey as it is jammy. Fruition have always been good at infusing the traditional into their progressive sounds. An essential band of the modern jamgrass movement.

“My Oh My / Boll Weevil” – Punch Brothers

Okay, now just because they can also play classical doesn’t mean Punch Brothers aren’t a jamgrass band! It’s bluegrass, it’s jam band, it’s jamgrass. I mean, you can’t be a string band playing that many Radiohead covers and not be considered jamgrass, right? Right.

“Coming Back To You” – Town Mountain

North Carolina has birthed some high-quality jamgrass over the years. Another band we’d wish out of retirement if we could, Town Mountain combined jam band appeal with country twang and bluegrass drive (and silliness, too). They were jamgrass even before they added a drum kit and a pedal steel, but towards the end of their tenure there they seemed to creep ever closer to the jammy center.

“One Horse Town” – Michael Cleveland & Flamekeeper Featuring Charlie Starr

Fiddling phenom Michael Cleveland is as traditional as they get, but whether in his work with Jason Carter or his many jaw-dropping features – with Béla Fleck, or Billy Strings, or Tommy Emmanuel, or whomever – he’s known to shred his way through some jamgrass, too. Partnering here with Charlie Starr of Southern rock group Blackberry Smoke, Cleveland and his band Flamekeeper are remarkably jamgrass.

“Billy in the Lowground” – Kenny G, Ed Helms, Bryan Sutton, and Gabe Witcher

A virtual jam for pandemic times creates virtual jamgrass of the highest – and most random – sort! One of our crowning achievements across the history of BGS will be getting Kenny G in on a COVID benefit bluegrass jam. For Whiskey Sour Happy Hour, our pandemic-era virtual variety show, the sensational wind specialist performed “Billy in the Lowground” with Bryan Sutton, Gabe Witcher, and our co-founder Ed Helms. ICONIC. If Kenny G is playing bluegrass, it’s gotta be jamgrass.

“Turn Around” – Larry Campbell and Teresa Williams

Calling Larry Campbell and Teresa Williams “jamgrass artists” would be woefully reductive and simplistic. Still, it wouldn’t be right to exclude them from this list. Across their varied and diverse careers they’ve collaborated, recorded, and performed with some absolutely seminal figures in Americana, jam band, and bluegrass. Here, we caught up with the duo while sailing aboard our favorite roots music cruise, Cayamo.

“How Many Times” – Rainbow Girls

Something about Rainbow Girls is just a perfect fit for a jamgrass playlist – and we don’t just mean the rainbows. Also captured aboard a Cayamo voyage, this Bob Marley cover by the Bay Area-bwased folk group encapsulates so many of the facets that we love about jamgrass, from the material to the joy they bring forth in the music to their humor and community mindset.

“House of the Rising Sun” – Peter Rowan, Sam Bush, and Friends

There wouldn’t be no jamgrass without these fellas! At MerleFest last year Sam Bush hosted the iconic Late Night Jam and there were quite a few Late Night-jamgrassy moments. Whenever jamgrass gets to the point of having its own canon of recognizable material, like bluegrass, old-time, jazz, and others, “House of the Rising Sun” will surely be found among those songs. Absolutely nonnegotiable.

“Takes So Long, Goes So Fast” – Lindsay Lou

Decked out in snow gear, in a gondola above Lake Tahoe, with a bunch of hippies and wooks and music fans at WinterWonderGrass? Yep, that might be jamgrass. Lindsay Lou has become a stalwart in the younger jamgrass generations, and certainly not just because of her many connections to Billy Strings. As a performer herself or a collaborator or artist at large, she’s a favorite at jamgrass festivals and events.

“Fishin’ in the Dark” – AJ Lee & Blue Summit

Jamgrass filtering down through the generations! A fantastic up-and-coming bluegrass band, AJ Lee & Blue Summit, offer their rendition of a jamgrass classic first recorded by Nitty Gritty Dirt Band. Who are Nitty Gritty if not a jamgrass outfit? While AJ Lee and band are much more than “just” jamgrass, they fit that moniker oh so well. This Sierragrass Sitch Session has been a fan favorite.

“Lonesome Dove” – Mountain Grass Unit

Shouldering the jamgrass mantle for Gen Z, Mountain Grass Unit have jammed with everyone from Billy Strings to Kesha to Shania Twain. These fellas are making a name for themselves right at the very center of the jamgrass universe, but while still carving out their own sound and their own identity. An exciting act to be watching and following along with at this juncture, their new album is set for release in late August.

“The Missing Stair” – Big Richard

You know what’s a prerequisite for being or becoming a jamgrass band? Big Richard energy. This group of supremely talented women have got it. We’d love to see them on more jam band and jamgrass festival lineups – a welcome palate cleanser, indeed.

“Fiery Gizzard” – the Travelin’ McCourys

Del McCoury Band have been known to dip a toe in the jamgrass waters regularly, but when the boys are “released” from their duties with their father and bandleader and go out as the Travelin’ McCourys is when they really lean into the jams. Their live shows are some of the highest quality jamgrass out there, the most elite bluegrass virtuosity lent to the jammiest, rip-roaringest tunes and songs.

“The Road Is a River” – Jim Lauderdale

Country’s modern renaissance man Jim Lauderdale is oh-so-many things – and jamgrass is one of them. With Lillie Mae and Frank Rische at his side, that seems especially true in this Rootsy Summer Session shot in Sweden. With as much tai chi as Lauderdale does, of course he belongs on this list!

“High Country” – Leftover Salmon

Leftover Salmon are one of THE most important and impactful artisan purveyors of jamgrass around. We were lucky to finally get a Sitch Session with the group a few years ago at WinterWonderGrass in Colorado. WWG is one of the best jamgrass assemblages around these days, and the festival just announced BajaWonderGrass in Mexico for April 2027.

“Weight of the World” – Clay Street Unit

Another group on the cutting edge of jamgrass and actively building its future is Clay Street Unit. Born out of the fertile jamgrass territories surrounding Denver, Colorado, the band just released their debut album earlier this year. So there’s still ample opportunity to get in on the “ground floor” of a group that is certainly going places.

“These Chickens Eat Fascists” – Pixie & the Partygrass Boys

We’d like to thank Pixie & the Partygrass Boys for representing anti-fascism in jamgrass. It’s an important beat and we need more folks giving us such a hilarious point of solidarity as “These Chickens Eat Fascists.” Two things jamgrass is always going to be: open and accepting of everyone, and a goddamn party!

“Not Quite Spring” – Kyle Tuttle

A premier banjoist in jamgrass, Kyle Tuttle has performed with so many greats in the subgenre, from Jeff Austin and Molly Tuttle to Lindsay Lou to Leftover Salmon – and many, many more. His own solo albums and solo shows (which are, gratefully, becoming more and more frequent) are jamgrassy top-to-bottom. If you’re lucky, catch him at Bluegrass Mondays at Dee’s Country Cocktail Lounge in Nashville these days, where he’s often holding court with impeccable bands backing him up.

“Islands In the Stream” – Love Canon

A jamgrass tributary in the mighty jamgrass river coursing towards the roiling jamgrass sea is cover songs from outside of bluegrass and roots music altogether. Ever since the Earl Scruggs Revue, New Grass Revival, and others in the earliest days, this has been an important plank in the jamgrass platform. Love Canon are one of the bands who did it best, offering bluegrassified versions of absolute bangers – like “Islands In the Stream,” here featuring Lauren Balthrop on vocals.
