Aynsley Dunbar and Alex Dmochowski both played on Michael Chapman's "Rainmaker" album, released in 1970.
The album has been re-released on CD by the Light In The Attic label, with six bonus tracks.
At the time, the both of them were part of The Aynsley Dunbar Retaliation.
Shortly thereafter, Aynsley joined The Mothers. & Zappa hired Alex a couple of years later to record on "Waka/Jawaka", "The Grand Wazoo" and "Apostrophe(')".
