Step one: produce an EP with two naked people staring out over the San Francisco landscape. Step two: write a band bio that describes this cover picture, and throw in some strange ramblings/possible song lyrics to make it seem as if you’re in a cult and looking for followers. Step three: eh, let’s just see how that last part plays out. Such is the quirky vibe of San Francisco-based Nova Albion, and who knows whether or not one can judge this book by its cover. The indie band plays a record-release show this Friday and, since the group trucks in the same amount of mystery as a unicorn, there’s no telling what exactly the performance will have in store. Test the waters and “join them” on Friday, Aug. 16, at Hopmonk Tavern. 224 Vintage Way, Novato. $10. 9pm. 415.892.6200.
