If you’re not going to drop acid, you’ll at least want to get rip-roaring stoned (it’s legal, after all) before heading out to see this experimental Japanese psychedelic collective led by guitarist Kawabata Makoto, who views himself less as a songwriter and more as a conduit for all the sounds of the cosmos.

The group’s songs move from walls of noisy guitars to ambient synths, and lack any kind of traditional structure. It’s abstract art, to be sure; if you can open your third eye, you’ll probably have a much better time taking it all in. With Master Musicians of Bukkake, Tjutjuna. Chop Suey, 1325 E. Madison St., 324-8005. 8 p.m. $12 adv./$15 DOS.
