Auditory adventures await, if you so choose. Every year experimental musicians from all over the nation (and even the world!) descend upon Sacramento for the annual Norcal Noisefest. Sometimes loud, sometimes quiet, often weird, Noisefest is not for the faint of heart. If you consider yourself an adventurous consumer of music and art, consider hitting up Luna’s Cafe on Sept. 30 or Cafe Colonial on Oct. 1 and 2 to partake in the 20th annual celebration of “sound art.” Groups like Uberkunst, Instagon, Big City Orchestra, Liver Cancer, Dental Work, Lords of Outland, Xome and so many others are eager to expand your mind. Tickets are just $10 per day, all ages are welcome and weekend passes are available at Norcalnoisefest.com, where you will also find a plethora of information on this year’s events, as well as a history of the festival and recordings from past shows. This year there are even two satellite shows, Sept. 29 at The Luggage Store Gallery in San Francisco, and Oct. 3 back at Luna’s for a post-fest decompression gig. The all too common verse/chorus/verse song structure can be damned, and the “millennial whoop” can go to straight to hell, because the Norcal Noisefest is back to remind us that music can and should be off-center, avant-garde and interesting. Long live the noise!
