Any time you see either The Tremolords or The Belltowers on a bill around here, you know you’re not simply getting some good bands but a good party. That’s because these 1960s-inspired groups are deep in their devotion, masters of their craft and come with a spirited following of garage-rock diehards who shake more per-capita ass than almost all of the city’s other underground subcultures. This time, the two beloved Orlando bands bookend notable St. Pete guests Pretty Voices, who’ll be a natural fit with their strapping blend of classic garage, power pop and rock&roll.
