Tucson, Arizona’s Lenguas Largas is an experimental, art-rock garage band with a custom sound that mixes electronic flourishes with DIY, lo-fi production, jangly guitars and sing-song vocal harmonies. Kind of a cool trick, actually. You can catch these desert creatures over at the Siren’s Song Tavern tonight at 8 p.m. As I have no idea what the cover charge is, bring some cash.
