The most important recording of the 1990s grunge era wasn't made by some alt rock star. It was a covert audio recording of two drunken men living in a small flat in San Francisco, who spent their available free time yelling, screaming, hitting and generally abusing each other. The tapes went on to inspire a cult following, spawning sell-out CDs, comic artworks by Dan Clowes (Ghostworld), stage-plays, music from the likes of Devo, and a Hollywood feeding frenzy.
