Despite all the recent turmoil at San Francisco’s now-purgatorial college radio station, KUSF, the annual Rock ’n’ Swap music fair will go on as planned. Held this Sunday, February 13, at the University of San Francisco‘s McLaren Hall, the event will feature a wide variety of vinyl, CDs, DVDs, posters, and collectors items. It runs from 10 a.m. to 3 p.m., and costs $3 admission. Incidentally, a whole spate of other “Save KUSF” events are also slated for the near future, including a block party this Wednesday at Borderlands Cafe (870 Valencia St., San Francisco). That one starts at 7 p.m.
