Houston punk history and the city's newer underground energy collide at Discovery Green for a louder edition of the free Deep in the Heart series. Long-running 30footFALL leads the bill, Municipal Bats brings a jagged mix of noise rock and post-punk, and DJ Mexican Blackbird fills the gaps with funk, cumbia, soul, salsa, Tejano, and deep vinyl finds. Expect an outdoor downtown crowd, brisk sets, and a community concert that feels far less predictable than a standard park night.
