Ozomatli has been at the crossroads of music and activism for more than a decade, and its newest album, Don't Mess With the Dragon, is all about personal responsibility. "People growing up, people taking care of their own lives. The healthier people get, the better the music gets," said bassist Wil-Dog Abers on the band's Web site. Tracks on Dragon address the Bush administration's response to Hurricane Katrina devastation and more. Doors open at 8 p.m. Wednesday at Sonar, 407 E. Saratoga St. Tickets are $17.
