Resent mainstream record releases? Thrive on dollar bins? Derive pride and sense of self-worth from sheer obsurity of your record collection? Then boy, do we have the event for you: KUSF 90.3 FM’s Rock N Swap record collector’s fair. Held at McLaren Hall on the University of San Francisco campus on Sunday, December 17, the Rock N Swap “gives self-sufficient traders the chance to showcase their personal collection of memorabilia.” Bring your egos, ’cause you’re gonna need ’em. And bring a few singles: general admission is $3. If you show up early and drop $15, they’ll let you in for the Early Bird Shopping Special (5:30 a.m.-10 a.m.); the main event runs from 10 a.m.-4 p.m. “The affair…is ideal for diehard collectors and vinyl junkies,” reads the press release. “Buyers, sellers, and traders travel all over the world to attend this event,” it claims. “Rock N Swap is the perfet place to find rare Beatle recordings or Japanese imports.” You may even be able to find that rare Creed EP from Holland you’ve been searching for.
