Ever since Robert Drake, Melissa Torres, and Dave Ghoul organized Philly’s first Zombie Crawl in 2006, it has elevated itself into becoming one of South Street’s most decorated traditions. It became so popular that it led to a second annual happening in the Zombie Prom, that first kicked off on September of 2007 at The Trocadero. Last year the call for a summer event was answered in the form of The Zombie Beach Party, and tonight the legions of the undead are once again ready to raid The Troc in a flesh eating frenzy. While the Terror Behind The Walls make-up crew provides the rotting flesh touches for those who arrive out of costume, Robert Drake and Dave Ghoul will be providing brain eating boogies for zombies to Thriller dance to. And since it wouldn’t be a good beach party without a little surf guitar, and Philly surf punks, The Slotcars,are ready to answer the call of the damned. For a few years, Dave Roller and the ladies X have been breaking out tunes that will make fans of The Ramones and The Queers happy. And songs like “The Slotcars Theme” and “Surfing New Jersey” are perfect for slam dancing in the pale moonlight. The Trocadero, 1003 Arch St., 8pm, $10, 21+ – Bill McThrill
