Pink Floyd - Wish You Were Here: ''Quad Mix'' And ''Deff Mix'' (2CD) (1997)

Wish You Were Here: ''Quad Mix'' And ''Deff Mix'' is a 2CD bootleg by Pink Floyd. Released by the Highland label, it is a conversion from the quadraphonic 8-track tape, where the forward channels are the "quad" (or quadraphonic) mix and the rear channels are called the "deff" mix.
