Underground credibility: you spend your whole career trying to maintain it, only to realise that 15 years have passed and you're still constantly broke. Such is the lot of most of the bands appearing at this all-day event, which takes its title from a compilation released in 2000. If you'd stumbled through the doors of the original Koenji 20000V live house back then, there's a good chance that you might have caught a set by the likes of Bossston Cruizing Mania, Electric Eel Shock, Panicsmile or Natsumen, all of whom will be present at WWW. While those groups have all gone on to enjoy a certain amount of success and wider recognition, the same can't be said of some of others on the bill – not least the event's organisers, noise performance artists Do Thank Anal. If you want a potted history of Tokyo's underground live scene, you could do a lot worse. See below for complete lineup.
