Wednesday night’s show at the 9:30 Club was the start of a high-profile tour for Middle Brother. It’s a side-project for its members, all of whom have highly respected bands on the cusp of greatness of their own to tend to. For less-talented musicians, gambling time away from their primary projects might kill the hard-won momentum they’d built up. For the members of Middle Brother—Dawes’ Taylor Goldsmith, Deer Tick’s John McCaulay and Delta Spirit’s Matt Vasquez, all of them darlings of the indie music culture—the side project turned out to be a shot of adrenaline for a bunch of guys already riding pretty high on their own. Wednesday’s show took some seriously high-energy bands, tumbled their members together in a free-for-all of booze, musicianship and friendship, and spit out a rocket fuel concoction that propelled its members even higher. It ranked among the best I’ve seen on the 9:30 Club stage. So, first things first: Thank you, guys. That was a hell of a night.
