CRITIC’S PICK: How can two Switzerland-based brothers and instrumental guitarists, playing a mix of often atmospheric music inspired by Spaghetti Westerns and Ry Cooder sell out this thousand seat venue with hardly any promotion and even less radio play? Certainly, releasing their most recent album on Dan Auerbach’s Easy Eye imprint helped. But with a retro approach comparable to little else, they have carved a specialized niche in world-inspired Americana that clearly resonates with more than a cult audience. It’s a hypnotic, inimitable, often moody sound. See if you can find a ticket. — Hal Horowitz
