Mondays are typically no cover at Costa Mesa's Detroit Bar, but special circumstances call for special measures, like tonight. They're hosting a KCRW-presented show with Argentinian folktronic artist Juana Molina, who will be appealing with her full band. She just released her fifth album, Un Dia, last year, and this is the fourth of five California dates this month for her. Previously scheduled February Monday residents Free Moral Agents open. Show is $14; next Monday, things are free again for the last February appearance from Free Moral Agents.
