As Shinobi Ninja's penchant for on-stage personas might imply, there's a Jekyll-and-Hyde dichotomy to the loosely sutured genres in their songs. Guitarist Maniac Mike serves up Pantera-thrash riffs that give way to glassy chord structure and hip-hop beats when Baby G lays down the rhymes. Though the mid-song transitions are about as subtle and graceful as Beverly Hills Ninja – these are pretty much rock songs with a legit hip-hop section plunked in – that's OK. Tracks like "ILL ISH," which expresses Ninja's love of drinking, smoking weed and all types of ill shit (our kind of people), really gain charm from the random. 8 p.m. July 5, Jack Rabbits, San Marco, $8.
