Visiting literal makers of music, crafters of instruments and sounds. Luthier Wayne Henderson takes us to his Virginia workshop for an old-time country jam session with Doc Watson. Robert Moog, of Moog Synthesizer fame, tells about creating electronic keyboards, and Sam Phillips of Memphis’ Sun Records recounts the reverb slap that shaped the sound of rock and rollers Elvis Presley, Carl Perkins, Jerry Lee Lewis and Johnny Cash.

Two hours of music surrounding the forefather of the blues, Robert Johnson. The guitarist and singer is remembered by four other Delta bluesmen: guitarist Johnny Shines rode the rails with Johnson in the 1930s, pianist and guitarist Henry Townsend jammed with him, Robert Junior Lockwood is Johnson’s stepson and the late diddly-bow player Lonnie Pitchford followed in his footsteps. We’ll also hear Johnson tunes in the hands of latter-day artists the Rolling Stones and the Red Hot Chili Peppers.
