There was only one prize-winning teenager carrying stones big enough to say thanks, but no thanks to Roy Acuff. Only one son of Kentucky finding a light of inspiration from Bill Monroe and his Blue Grass Boys and catching a fire from Bob Marley and The Wailers. Only one progressive hippie allying with like-minded conspirators, rolling out the New Grass revolution, and then leaving the genre's torch-bearing band behind as it reached its commercial peak.

There is only one consensus pick of peers and predecessors, of the traditionalists, the rebels, and the next gen devotees. Music's ultimate inside outsider. Or is it outside insider? There is only one Sam Bush.

Paul Hoffman is a singer, songwriter and the mandolin player of the critically acclaimed and internationally touring Americana/Rock band Greensky Bluegrass. Raised in Muskegon, MI, he immersed himself in community theatre, numerous school choirs and productions, and classic rock fueled boat shed jams. A collegiate endeavor in English Literature led to Kalamazoo, MI which catalyzed the formation and became the home base for Greensky. From humble beginnings, the band quickly became a festival favorite, having performed at such iconic events as Bonnaroo, Austin City Limits Festival, Stagecoach, Telluride Bluegrass Festival and countless others in addition to headlining sold out performances at revered venues such as Red Rocks Amphitheater, Ryman Auditorium, and The Chicago Theatre. "Greensky are hardly strictly bluegrass and, yet, representing the genre for a whole new generation," claimed Rolling Stone in 2010. Recorded works have landed on several Billboard charts including #1 placement on the Bluegrass charts.
