Delta Spirit + Jeff the Brotherhood + Fidlar

San Diego’s Delta Spirit creates songs that aren't encumbered with a need to be overly catchy; instead, the band explores dark, spare moments while constructing touching epics. Tonight the quintet comes to town with its eponymous album and Jeff the Brotherhood, the Nashville brother act of Jake and Jamin Orrall, who show off their burly, hooky, proudly retro indie rock—custom-built for a beer-hoisting blowout.
