Bittan played an important part in the sound Stevie Nicks created for her solo debut away from Fleetwood Mac, "Bella Donna" (1981). About the time that the album reached number one in the United States (and Springsteen's "The River" Tour concluded), Bittan joined as a sideman on a short tour with Nicks along with some of the other top musicians of the day: Benmont Tench on organ, bass guitarist Bob Glaub, Waddy Wachtel on guitar, Russ Kunkel on drums, and Bobbeye Hall on percussion. Bittan also played on Nicks' second solo album "The Wild Heart" and has continued to play with her sporadically.
