While you were sleeping, the Athens underground erupted into a prismatic display of synthy psychedelia, a nouveau showcase of drones, loops and other such sound manipulation. Never mind the "rock and roll is dead" chatter emanating from the tubes; what our guitarless local groups are putting forth is not so much a rejection of punk but an otherworldly embrace of its most centric principles. The lineup for the second installment in the incipient Experimentaler series includes partnered sonic scientists Grant and Rachel Evans (the latter performing as Motion Sickness of Time Travel), along with radar-skirting psych tribe Cult of Riggonia, beat-heavy visualists Future Ape Tapes and dance-damaged vibe hunters The Dream Scene, to name just a few of the two-day event's many guests.
