The 2012 Cosmic Convergence Festival descends upon The Sugar Mill on the day of the reported Mayan apocalypse in tongue-in-cheek hopes that its head-bopping tunes, atmospheric grooves, and vintage rock ‘n’ roll will stave off the end of the world. The 12-hour music extravaganza, hosted by Giorgio A. Tsoukalos, the star of History Channel’s Ancient Aliens, is fueled by local food trucks. 22 acts take over two aptly named performance spaces: the Mothership Stage and the Satellite Stage. At midnight, headliners Ghostland Observatory transport their inimitable blend of psychedelic rock and electronica to the former. The duo, who has been described as “Freddie Mercury-helms-Daft Punk,” cranks out their infectious beats against Aaron Behrens’ funky falsetto and a flurry of lights timed to the rhythms of audience members’ heartbeats.

The one-man band and puppeteer that make up Quintron and Miss Pussycat dazzle onlookers with their frenetic, interactive set on the Mothership Stage beginning at 10:50 p.m. As Miss Pussycat boogies with handheld puppets and lends her vocals to songs such as “Shoplifter” and “Place Unknown,” Quintron simultaneously commands the microphone, keyboards, and drums in a feat of dynamic multitasking.

Earlier in the day on the Satellite Stage, The Local Skank, a mostly all-female ska band from New Orleans, charms audiences with their musical genre’s staple blend of trombone and trumpet, upstroke guitar, and walking bass lines. Also making a celebratory appearance at the fest are local horn collective Hot 8 Brass Band, blues man Derrick Freeman, and MC Trachiotomy, an enigmatic entertainer who fuses spoken word, psychedelia, and puzzling references to throat surgeries. Attendees can rock out knowing their admission prices went to a good cause; a portion of the fest’s proceeds benefit the Peter Mayhew Foundation. Founded by the actor famous for playing Chewbacca in the Star Wars films, the charity develops programs to help children who are at-risk or have special needs.
