One week after wrapping up a string of shared shows in the Southwest, Jenny Lewis and Ryan Adams teamed up again last night, when both songwriters hit the stage during an episode of Jimmy Kimmel Live . Lewis was the show’s musical guest, in her last gig of a busy year spent creating, releasing and promoting her third solo album, The Voyager . She brought along Adams for the ride, adding her producer to a large, all-star backup band that also featured several other solo artists, including guitarist Megan McCormick, keyboardist Natalie Prass and harmony vocalist Z Berg.
