Hailing from Birmingham, Alabama, Mountain Grass Unit has rapidly emerged as one of the most electrifying young bands in modern bluegrass, fusing razor-sharp picking, fearless improvisation, and four-part harmony into a sound that feels both rooted and revolutionary. The quartet — Drury Anderson (mandolin, vocals), Luke Black (guitar, vocals), Josiah Nelson (fiddle, vocals), and Sam Wilson (bass, vocals) — first turned heads with their 2024 EP Runnin’ From Trouble, but 2025 proved to be their true breakthrough year. The band logged nearly 100 national tour dates, sold out over thirty headline shows, and delivered standout festival performances at Telluride Bluegrass, DelFest, Northlands, and WinterWonderGrass.

Rolling Stone praised them as the “surprise show” of Telluride, while Saving Country Music declared them the “next big band in bluegrass,” with further national spotlight through exclusive live sessions with Paste, Relix, and No Depression, cementing their arrival on the national stage. Their momentum peaked during IBMA week, where they earned the International Bluegrass Music Association’s Momentum Artist of the Year award, a defining milestone in a year of exponential growth.

Now in the studio crafting their next full-length album, due late summer, and fresh off support runs with genre leaders like The Infamous Stringdusters and Kitchen Dwellers, the band continues to expand its reach. Along the way, they’ve shared stages with legends like Billy Strings and Greensky Bluegrass in a series of high-profile moments that underscore the respect they’ve earned from the genre’s leading voices. Mountain Grass Unit isn’t simply riding bluegrass’s current resurgence; they are helping steer it, staking their claim as one of the most vital and forward-looking young bands in American roots music today.
