Turn on, tune in: John Cage's symphony for 12 radios

"One evening in May 1951, at the McMillin theatre at Columbia University, New York, a conductor, wearing tails and a stiff bib and tucker, walked out on stage to conduct an ensemble of 24 players. The musicians were snuggled in pairs around 12 portable radios, and the conductor was John Cage. He was also the composer of the piece that was about to be premiered, Imaginary Landscape No 4."
