When Dan Auerbach is one of your biggest fans, you’re probably doing something right. Of rock duo JEFF the Brotherhood the Black Keys front man opined, “JEFF the Brotherhood are the next big name in showbiz.” He’s right, and not just because of the all-caps thing — “big name,” get it? JTB’s latest record, Hypnotic Nights — released on Warner Bros. and co-produced by Auerbach — is a bruising blend of garage and psych rock that represents a musical maturation, yet harks to the duo’s gritty DIY roots. Catch JTB at the Higher Ground Showcase Lounge in South Burlington on Wednesday, June 10, with Gymshorts and locals Sleeping In.
