Hollow from Wild Animals by Trampled by Turtles
Trampled by Turtles are from Duluth, Minnesota and were initially formed in 2003. While the members were newcomers to playing as a fully acoustic band, they quickly began carving out a fast, frenetic sound that owed as much to rock & roll as bluegrass.
They've gone on to chart on Billboard, appear on TV, major festivals and tour relentlessly around the world.
