From Wikipedia.....After leaving Hawkwind the first time, Nik Turner holidayed in Egypt and while visiting the Great Pyramid of Giza he was given three hours inside the King's Chamber to record some flute music. On returning to England, Steve Hillage cleaned up the tapes and assembled the Sphynx band featuring Hawkwind's Alan Powell, Gong's Mike Howlett and Tim Blake, and Harry Williamson to record music augmenting the original flute tracks while Turner adapted lyrics from the Egyptian Book of the Dead. The album was released as Xitintoday on Charisma records in 1978 and the band toured, played festivals including Deeply Vale Festivals (later released as a CD), Glastonbury Festival (part of which was broadcast BBC television) and his own themed Bohemian Love-In all day festival at the Roundhouse.
