Duluth bluegrass heroes Trampled by Turtles returned in May with Life Is Good on the Open Road, their first album in four years and third to debut at No. 1 on Billboard’s bluegrass chart. The album followed a hiatus the band took to pursue other endeavors (including frontman Dave Simonett’s 2017 post-divorce album as Dead Man Winter), and they sound successfully recommitted and chemistry-fueled. TBT is the only Minnesota act headlining a Grandstand performance at this year’s State Fair. With Lord Huron and Lissie.
