In 1975, Walden moved to Los Angeles and spent the rest of the decade performing as a solo artist and supporting artists such as Stevie Wonder, Donna Summer, Chaka Khan, and Eric Burdon. Notably, in 1975-6 he again filled in for Paul Kossoff as a session musician on Back Street Crawler's Second Street album. By the mid-1980s, television agents and producers became aware of Walden through his local performances in Santa Monica. When approached to score a new television show, Walden had mixed feelings but accepted the offer.
