Heartless Bastards and Hacienda returned to St. Louis for a packed show at the Firebird.

Hacienda, an impressively-bearded four-piece family band from San Antonio, opened for Heartless Bastards last night at the Firebird. While the bands aren't labelmates, their styles are somewhat similar and make for a well-paired touring team.

Every note Erika Wennerstrom sings is fully soaked with heart despite the name of her band -- Heartless Bastards.

Followers of Heartless Bastards crave the trio's blues-punk garage rock with its churning guitar, Erika Wennerstrom's distinctly rough voice and heartfelt lyrics. The band continues its stylistic journey on The Mountain. Will fans appreciate this evolution or deem it heartless? Decide for yourself via a live performance on Rocket 88.
