Les Paul - Extraordinaire Musician and Inventor

Without him, we might never heard Rock & Roll. He is also credited with many recording innovations, including overdubbing (also known as sound on sound), delay effects such as tape delay, phasing effects, and multitrack recording.

Here is a short documentary I found out from YouTube that literally explain a bit about him.

"What's your name?

It's on your guitar... - Les Paul"

Les Paul died on August 12, 2009 at the age 94. A great loss to the music world. RIP
