Arzachel
In mid-1969, to capitalise on the psychedelic rock market, Stewart, Campbell and Brooks contributed to the one-off studio project Arzachel, named after a moon crater. Also featured in that project was Steve Hillage (on summer holiday from university), who'd also been a member of the pre-Egg band Uriel. Egg were by that time under contract to Decca, therefore all credited with pseudonyms.
