In Terry Zwigoff and Daniel Clowes’ Art School Confidential, there’s a scene where Joel David Moore’s character convinces new kid Max Minghella to go to a pretty dreadful student art opening on the sole basis that all art shows are required, by tradition and by the need to attract a crowd, to have free booze and snacks. That may or may not be a nice thing to think about, but let’s face it — we’ve all been guilty of making a brief 15-minute appearance somewhere just to see which of our acquaintances stopped in to also catch a buzz on the complimentary chardonnay. However, we’ve got a feeling that Concurrent, which is opening this Friday at the Knights of Columbus Building, will definitely not be one of those shows you’ll need to sneak out of while appearing to have a sudden emergency. Eleven contemporary artists from the Charleston area, including Liz Vaughan, Tony Csavas, Camela Guevara, and Rebecca West Fraser, will be showing new works at the large building above Artist & Craftsman — and, true to form, there will be beer provided by Holy City Brewing. But we’re pretty sure that even if some ignorant folks just go for the booze (or for the DJ set by Party Dad), they’re definitely going to stick around once they see what’s up on the walls.
