The KLF Burn a Million Pounds (1994)
What kind of superstar band could afford to burn a million pounds just for the hell of it? Apparently the KLF, although the subversive electronic duo of Bill Drummond and Jimmy Cauty had only recently tasted massive success in England when, in 1994, they burned exactly that amount of cash as an act of performance art. While the act may have succeeded in that aspect, it caused major head-scratching and criticism of the group, which had already announced its retirement (via an open letter attached to a dead sheep, no less). Years later Drummond himself expressed regret for the stunt; the money had originally been intended as a charitable fund to help struggling artists, until Drummond declared "that struggling artists are meant to struggle, that's the whole point."
