Smithsonian Folkways remembers guitar master and innovator Les Paul, who died last week. The legendary musician, whose signature solid-body electric guitar and numerous recording studio innovations have forever changed popular music, performed on two Smithsonian Folkways recordings during the late 1940s. He leads a band through the improvised Jazz at the Philharmonic- Blues, Part 3 from the 1966 release The Asch Recordings, 1939 to 1947 - Vol. 1: Blues, Gospel, and Jazz and sings Born to Lose with his wife Mary Ford on the 1967 companion album The Asch Recordings, 1939 to 1945 - Vol. 2.
