Rocked-out psychedelic jazz meets jazzy psychedelic rock in this well-matched double-header. Both groups have been honing their live chops as of late. Rotary Downs sounds at times like a moody Ennio Morricone soundtrack and at times like a high-school marching band on mushrooms. It has returned from a couple of high-profile gigs at the Bonnaroo Music Festival and northern California's High Sierra Music Festival. Other Planets (pictured) are at the end of a three-month-long residency at the Dragon's Den. This final night in the series will serve as both a tag-team recording for a live album featuring both bands and a release party for the Planets' third album, Holiday for Vacationers
, which is possibly its best mashup of weird wizardry yet. The combo melds psych-rock and space-jazz into a smoking, burbling cocktail of delicious poison that's heavy with Frank Zappa influences, plus equal parts Syd Barrett, Brian Wilson and a smidge of Camper van Beethoven. Its horns can soar like Alvin Batiste at his most cosmonautical or lilt sloppily like Sgt. Pepper
. Tracks like the bitingly creepy 'Happy Time at the Mall" burrow into your brain as hypnotically as a Zappa opus. Tickets $7. Alison Fensterstock
