Observe the essential breakbeat in its natural habitat at Future Primitive Soundsession's "21st Century Urban Breakbeats." This exhibition will encompass the kinetic rhythms of the Chemical Brothers, the jungle groove of Goldie, the old-school hip hop of Afrika Bambaataa, and the trip-hop journeys of Coldcut. Displays of DJ skill will include the Cut Chemist, an underground hip-hop legend who performs, produces, and spins in L.A.; DJs Quest and Cue -- two-thirds of the Space Travelers, known for their breaks compilations on Bulletproof Records -- who will astonish with their combined speed and rare samples on four turntables; the South Bay's Peanut Butter Wolf, whose Step on Our Ego's? has received national attention for its unusual use of white noise and echoes; the Phunckateck Crew -- DJs Noel and U.F.O. -- who have been at the forefront of San Francisco's burgeoning jungle scene for the last two years; Felix the Dog, a British expatriate who is among San Francisco's most innovative DJs and co-founder of the Black Diamond Experience; and resident DJs Grey-V and Anna. The excursion begins at 9 p.m. on Saturday, Nov. 9, at Big Heart City; call 905-8868. ... Halloween need never end, not when Rent Romus is in town. The jazzmeister has returned in time to herald the darkening days of the hemisphere's yearly slumber with a tribute to things that go bump in the night. "Raven's Gate" explores the poetry and prose of opiate maven Edgar Allen Poe as voiced by Mantra Ben Ya'akova; jazzy dirges will be supplied by Rent Romus and the Lords of Outland with everything but Christmas cheer. The macabre evening will be held at 7 p.m. on Sunday, Nov. 10, at the 848 Divisadero Community Space; call (510) 841-7855. ... In a year when so many first- and second-generation punks have come out of the woodwork to completely humiliate themselves, it was heartening to have White Light White Heat White Trash hit the airwaves. Social Distortion has managed the near impossible: to age with dignity and still release a shit-hot record that, despite its reflective nature, smacks of grit and back-alley grime -- something Social D offspring have sadly failed to deliver. The show at the Great American Music Hall this past July found Mike Ness and the boys in high, sweaty form (road-tested musicianship can, on occasion, fill the shoes of youthful abandon). While the crowd consisted of the anticipated blend of greaseballs who craved Mommy's Little Monster and their younger counterparts who had only discovered Social D via Live 105 and their latest single "I Was Wrong," no one left unhappy. The band ran the gamut with a tight, elated energy that could not be achieved back in the day when musicians were expected to be uniformly fucked up. Ness is still sexy as hell -- soft middle and thinning hair included. It's not just any man who can wear eyeliner for 15 years without becoming a shameful parody. SoCal compatriots the 22 Jacks (including members of WAX, the Adolescents, face to face, and No Use for a Name) will open the upcoming show with crisp, infectious power pop. The Jacks recently came out of the studio backing Joey Ramone on "I'll Be With You Tonight" -- Ramone's contribution to an upcoming Cheap Trick tribute album. Said the Jacks' frontman, Joe Sib, "Working with Joey was great. I'd be doing vocals with him and, all of the sudden it would hit me, 'Hey, I'm singing with Joey Ramone!' I'd have to go outside for air until I could remember how to sing again." D Generation also shares the bill. The show begins at 7 p.m. on Monday, Nov. 11, at the Trocadero; call 995-4600.
