The time Aphex Twin opened for Björk
Shuffle mode has just reminded me of the time Richard D James (best known as Aphex Twin), using the pseudonym DJ Smojphace, opened for Björk at the Hammersmith Apollo in 2003.
From the YouTube video description:
For almost 2 hours Richard played nothing but “noise and feedback” from the backstage, only appearing in stage to cheerily wave goodbye in front of a very, very pissed audience.
Listen to the booing! Delightfully funny.
