Les Pink Floyd sont les 1ers à utiliser un son à 4 canaux au London's Queen Elizabeth Hall. 

1967: Pink Floyd performs the first-ever surround sound concert at "Games for May," a lavish affair at London's Queen Elizabeth Hall where the band debuts its custom-made quadraphonic speaker system. The technological breakthrough not only amazes and confuses the mass of stoned concert-goers, but it goes on to raise the standard of what audiences would come to expect from a live rock performance.
