Following the departure of original bassist Martin Dresden and drummer Hans Cleuver in 1970, the band recruited Cyril Havermans and Pierre van der Linden, respectively, and prepared material for a new album.

[5] Focus was formed in Amsterdam in 1969 by keyboardist, vocalist, and flautist Thijs van Leer, bassist Martin Dresden, drummer Hans Cleuver, and guitarist Jan Akkerman.

"Hocus Pocus" is a rock song that features van Leer yodelling, eefing, scat singing, and whistling.

"Moving Waves", a piano and vocal solo by van Leer, features lyrics by Sufi singer, poet, and teacher Inayat Khan.

The track is in fifteen distinct sections, and the suite opens with an uncredited melody from the opera L'Orfeo by Monteverdi.

"Tommy" features a guitar solo and was named and written by Tom Barlage of the Dutch fusion band Solution.

"Euridice" is a classical lied which segues into the Gregorian-inspired "Dayglow" and followed by van der Linden's drum solo, "Endless Road".
