Cossa Frenzy (Amorphous Music)
Excellent new release from local dance luminaries Bassnectar. Heavy, funky, and nasty, this is what you want to hear when you’re lost in the middle of the dance floor at 2 a.m. Clever little touches like the inclusion of classical-music samples are to be expected from a band that’s recently included a Pixies cover in their shows.
At Concourse Exhibition Center (635 8th Street, San Francisco) on December 31. 9 p.m., $75-$135
