Fri., Dec. 28, Mount Whateverest

Haven Underground, 9 p.m., $8-$12

Nestled in the foothills of Grass Valley, Mount Whateverest crafts tunes that are kind of trippy—but not in a totally stoner way (although if that's the way you roll … )—and seem to hail from a simpler, groovier era. Though the band describes its music as an amalgamation of Latin rock, grunge and shoegaze, the songs on its new self-titled album epitomize that Northern-California-foothills retro-hippie sound, but with a few twists. Songs such as “Room With No Sound” and “Kiss the Ring” marry Haight Street trip-out sessions with a garage-rock aesthetic that manages to feel fresh, not musty. The band celebrates with a CD-release party. 226 Broad Street in Nevada City,
