Scott, Karl, and Trent introduce us to the genius of Les Paul. Best known for the solid-body electric guitar, Les Paul was a prolific inventor and tinkerer. He also developed many of the techniques that formed the backbone of modern music recording, including multitracking, overdubbing, and tape effects. Scott says, "He's an interesting kind of genius because of the way it all came about." Les Paul will always hold a special place in the pantheon of American musical greats.
