Opal was an American band associated with the Paisley Underground and whose guiding force was David Roback, a guitarist and songwriter from Pacific Palisades. Roback graduated from high school in 1975 and in 1981 formed The Sidewalks who, renamed Rain Parade, were seminal within the Paisley Underground scene.
Roback quit Rain Parade in 1983 after the release of their debut and formed Clay Allison with Kendra Smith from The Dream Syndicate on bass and Keith Mitchell (drums). As Clay Allison the band released “Fell from the Sun” b/w “All Souls.” After they changed their name to Opal, they released two EPs, Fell from the Sun (1984) and Northern Line (1985), which were later combined and released as Early Recordings. Opal’s sole full-length, the mostly T.Rex-indebted (albeit almost narcoleptically laid back) Happy Nightmare Baby, followed in 1987.
