Les Paul dies at 94

Les Paul, the jazz guitarist who died on August 13 aged 94, invented the solid body electric guitar and revolutionised the sound of pop music recordings.

Known as "the Thomas Edison of the music industry", Les Paul pioneered multi-tracking – whereby instruments in a band or orchestra are recorded through separate, independently adjustable channels – and overdubbing, in which additional sound or music can be added after the original recording is made.
