The recording industry's top atonal composers gathered in Los Angeles Monday for the gala seventh annual Atony Awards. 'Tonight is hostile music's biggest night,' said Krzysztof Penderecki, nominee in the Most Dissonant Piece category. 'I can't tell you what a thrill it is to be here, surrounded by so many legends of arrhythmic cacophony.' The highlight of the evening is expected to be the awarding of the Olivier Messiaen Lifetime Achievement Award to Karlheinz Stockhausen for 'more than five decades of aggressively impenetrable anti-music.'
