Gotta love the Google thing today - a very cool tribute to the great Les Paul. It'd be hard to think of a more influential twentieth century musician, if you think about it. I mean, overdubbing and the electric guitar, what more could someone be asked to contribute? Anyone who uses either (or in most cases, both), which means virtually everyone in popular music, owes him a tip of the cap - and a serious re-listening to his recordings. The place to start, for me, is obvious: his work with the astonishing vocalist, Mary Ford (talk about a singer who is in tune!). Without these two pioneers, would we have had The Beach Boys or Queen? Or Led Zeppelin? Props needed. Here's a cool clip of the duo doing one of their most famous numbers: http://www.youtube.com/watch?v=e0ffdwBUL78.
