RIP Les Paul

Aw Heck.

Les Paul, whose innovations with the electric guitar and studio technology made him one of the most important figures in recorded music, has died. He was 94.

Paul died in White Plains, New York, from complications of severe pneumonia.

Paul was a guitar and electronics mastermind whose creations - such as multitrack recording, tape delay and the solid-body guitar that bears his name, the Gibson Les Paul - helped give rise to modern popular music, including rock 'n' roll.

No slouch on the guitar himself, he continued playing at clubs into his 90s despite being hampered by arthritis. (CNN)
