PREVIEW While something like the Treasure Island Music Festival can be summarized in a nutshell — a day of indie rock and a day of electronica — the annual Switchboard Music Festival defies classification. Traditionally, a lack of stylistic consistency is frowned upon in the music world — some artists spend years searching for their own reliable sound — Switchboard organizers say times have changed. With file-sharing and iTunes inundating fans with music, composers have the opportunity to go wild. On a song-by-song basis, good music is good music, regardless of who produced it or what genre it is.

Like many of the acts throughout the day, San Francisco's Aaron Novik seems to put his eggs in more baskets than the Easter Bunny. Novik is a self-described "clarinetist, composer, bandleader" who clearly has a propensity toward variety, as his projects span anywhere from psychedelic jazz to metal. At the festival, Novik will lead his traditional Jewish folk band the Yidiots, which includes Guardian editorial intern Dina Maccabee on violin.

Fellow musical butterfly Amy X Neuberg, the festival's headliner, will demonstrate her wide range of musical manifestations. Oakland composer Neuberg's performance centers on creative uses of her own voice, including some over-the-top opera, soft jazz tones, and spoken word — all looped in real time through a sequencer to create harmonies. Genres will bend and tear within her set and those of others, only to shatter with the first note of the following act.
