Two overworked words in popular culture today are "legend" and "icon, " but for Leon Russell, these terms are understatements. A member of the Rock and Roll Hall of Fame, he's one of the best multi-instrumentalists, songwriters and producers of the combined eras of rock 'n' roll, R&B and Americana. Now enjoying a major comeback sparked by his T-Bone Burnett-produced duo album with long-time fan Elton John, Russell is joined by all-star members of New Grass Revival: John Cowan, Butch Robins and Pat Flynn.
