Sam Bush is the undisputed Father of Newgrass — a mandolin powerhouse who stretched bluegrass beyond the boundaries of tradition and into wild, untamed possibility. With explosive rhythmic chop, fluid improvisation, and stage energy that blurs the line between roots music and rock rebellion, Bush helped redefine what acoustic music could be through his work with New Grass Revival, groundbreaking solo records, and collaborations with Emmylou Harris, Béla Fleck, Jerry Douglas, David Grisman, and countless festival-stage partners. His music is joyful, daring, percussive, soulful — proof that bluegrass can evolve without ever losing its heart. For generations of pickers, jamgrass fans, and festival faithful, Sam Bush isn’t just a musician — he’s a catalyst, a spark, and a lifelong invitation to play a little louder, looser, and freer.
