The one-liner on Isaac Terpstra (aka DJ Pandemonium) is that he's the local scene's premier goth and industrial record-spinner. The longer story is that he's been a nightclub fixture since 1995, and that he's played just about every club in the city, from dearly departed venues like the Palladium and the original Celebrities to newer spots like the Lotus and, well, the new Celebrities. When someone gets around to writing a history of Vancouver's electronic-music scene, Pandemonium will figure prominently.
