Arzachel has been played over 10 times on NTS, first on 28 September 2013. Arzachel's music has been featured on 19 episodes.

The band Arzachel was a pseudonym of the band Uriel, a short-lived English psychedelic rock band during the 1960s, composed of Steve Hillage, Dave Stewart, Clive Brooks and Mont Campbell. In 1969, after Uriel had broken up, they had an offer to record, though they had to change the name for legal reasons. After Hillage left to pursue his education, Stewart, Brooks and Campbell later continued as Egg, and Hillage's future band called Khan featured Stewart on keyboards.
