It takes summat special to coax the likes of The Prodigy and Gary Numan to an insalubrious Camden shi**ole (hey, it's a term of endearment) like the Purple Turtle. That summat special in this case is the return of underground alt rock heroes, Sulpher, who have been in remission for the last few years. Still, here they are, and here we are, packed in like sardines, waiting for what is, at least here tonight, the musical equivalent of the Second Coming.

There are few certainties in life: death, taxes, bad haircuts and what a Marilyn Manson record is going to sound like...

Beta Plus Embryo have been spending their time tweaking their sound to near-perfection and the debut album ‘Time Kills Everything' showcases their hypnotic sound and clockwork rhythm brilliantly.

Psychoanalysts have long debated Freud's contentious maxim that there are no such things as jokes. The Viennese pioneer himself asserted that jokes serve only one of two purposes, aggression or exposure; the hostile gag, which includes satire and defence mechanisms, and the second, the ribald or dirty joke. Thus the unconscious uses humour as a complex process of denial and yet, simultaneously, as an expression of unresolved rage. A more fascinating case study for budding Freudians, then, than Tenacious D would be hard to imagine.
