Grammy Award-winning guitar legend and inventor who changed the course of music with the electric guitar, Les Paul, died on Thursday in NY with pneumonia at 94.

As an inventor, Paul helped bring about the rise of rock 'n' roll and multitrack recording, which enables artists to record different instruments at different times, sing harmony with themselves, and then carefully balance the tracks in the finished recording.

Paul rose to fame for his fast and flashy jazz-guitar style. In the 1940s and early 1950s, he and his singer wife, Mary Ford had hits titled How High the Moon, The Tennessee Waltz, Vaya con Dios and The World is Waiting for the Sunrise.
