The Aynsley Dunbar Retaliation

Aynsley Dunbar led the Aynsley Dunbar Retaliation, who wrote the song "Warning", covered by Black Sabbath on their debut album. The Aynsley Dunbar Retaliation issued a number of albums. Dunbar was later the drummer for Frank Zappa's Mothers of Invention, featuring on albums such as Waka/Jawaka, and The Grand Wazoo, as well as the film 200 Motels. In 1974 he played on the soundtrack for "Down and Dirty Duck", a Chuck Swenson adult animated movie. In the mid 1970s, Dunbar joined Journey for their first four albums; he left and joined Jefferson Starship for three albums.

In 1985, Dunbar joined Whitesnake, and drummed on their 1987 album, Whitesnake. He also spent some time working with Eric Burdon and The Animals.

Dunbar was almost the drummer for The Jimi Hendrix Experience when in an audition Hendrix was unable to decide to pick either Dunbar or Mitch Mitchell - the latter won Hendrix's coin flip.
