This week’s big indie guitar showdown happens Tuesday Apr. 22, putting Black Lips (Phoenix Concert Theatre) up against We Are Scientists (Lee’s Palace). Breakups, breakdowns and a death in the band has not slowed down Black Lips. Eleven years on, these Atlanta garage legends continue to provoke and freak out audiences all over with their live show. This is, after all, the band which recorded their major label debut album, Los Valientes del Mundo Nuevo, live off the floor of a dive bar in Tijuana, Mexico, that the band solemnly described as "absolutely nuts." Then there was India 2009, where the dudes got up to some onstage “antics’ which so outraged the audience, the Lips fled the city and eventually the country, abandoning the tour on account of the very real fear they’d be busted and thrown in the slammer for "homosexual acts". The band’s view: “Ian and Cole kissed, some weiners got pulled out, people lost their shit.”
