In December 1967, they were featured on the BBC's Tomorrow's World, playing along to a light show, and the following year recorded some instrumental music for the film The Committee.

[6] The film More featured a young hitchhiker in Ibiza who had succumbed to heroin abuse with party scenes and drug taking.

Director Barbet Schroeder was a fan of Pink Floyd, and brought a rough cut of the film to London for them to work with.

[12] Mason and keyboardist Richard Wright co-wrote the instrumental "Up The Khyber", the only time the pair were credited as sole co-composers.

[15] The album also contains hard rock, such as "The Nile Song" and "Ibiza Bar",[12][16] as well as several instrumental tracks such as "Quicksilver" and "Main Theme", featuring their experimental and avant-garde approach.
