Keyboardist Matt Sjelin and guitarist Sean Mahoney claim the Trash Cats are “Duluth’s premier acoustic cat rock duo.” No argument here. For starters, no one else raises a paw to challenge them on the “cat rock” front. Not yet, anyway. And also the band does bring a lion’s-den collection of foot-stomping originals and old-school alt-rock covers to its shows. Purrrfect for felines and humans alike who enjoy acoustic duos strutting the fine line between wistful, trashy fun and fine musicianship.
