What? You say the Cave Singers are a folk band? ‘Cause they play, like, acoustic guitars, and guitarist Derek Fudesco has that signature sit-dance-rock thing? All good points. But trust me, they’re moving on. After seeing their amped-up set at Sasquatch! (where they were assisted by Fleet Foxes’ Morgan Henderson), the band took off their cloaks, Derek got out of his chair, and the quartet revealed themselves as who they’ve always been: a rock band with a thing for folk.
