 Khan recorded improvisations for the album, and Brook had to decide which sections, some of which were an hour long, were the best and how they were going to fit together, without having a structural point of reference to start with or aim towards.He had components recorded on multi-track tapes, and created each track part by part, overdubbing his instrumentation atop of it, a manual process that predated easy forms of digital editing.The album is considered a world fusion album, combining Khan's qawwali vocals with Brook's ambient production, and is often considered to be one of Khan's most experimental albums, featuring contributions from Senegalese and classically trained musicians.
