Where were you when you first heard it? I'll never forget. April 30, 1997, a Wednesday night: the first exclusive play on Radio 1's Evening Session. I'd expected 'The Bends' part two. What I heard instead was bizarre and breathtaking: six and a half minutes of spiralling melodies, twisted-metal dissonance, robot voices, and a desolate choral coda featuring the line, "The dust and the screaming, the vomit, the vomit."
