Trampled By Turtles

Hailing from Duluth, Minnesota, Trampled by Turtles are an alt country band caught between Dylan and Nirvana: plaintive bluegrass songs and speed-picked covers of indie rock. With old world Americana instrumentation (banjo, fiddle, harmonica, etc.), Turtles are open to interpretation as a strictly bluegrass band. However, their unconventional bouts of shredding and occasional use of drums invite people who don’t necessarily like bluegrass to, well, like bluegrass. Wild Animals, their seventh studio album, landed them on Letterman this July — a well-earned time slot thanks to songs like the expansive and melodic title track, and the melancholic waltz, “Repetition.”
