Jeez, two obituaries in a row! Les Paul who needs no introduction sadly died today from complications of severe pneumonia. He will be remembered not only as the maker of the guitar that bared his name as well as his many classic songs and inventions. Wikipedia credits his innovations being overdubbing, delay effects such as “sound on sound” and tape delay, phasing effects, and multitrack recording. He performed every Monday night at various venues for the past decade up till recently when he became ill.
