I'd never heard of WWDC (haven't listened to anything on the radio other than NPR since the 80s) but apparently they're having some sort of HFS-esque festival thingy on May 12th that includes the Silversun Pickups, no info on other possible acts or location. Now this may be merely an in-studio/on-air deal, but I was hoping someone could shed some light if there was any to be shed.
