It is the only Solution album to feature original vocalist and bassist Peter van der Sande, who was replaced by Guus Willemse around the time of the LP release.

Van der Sande provides raw vocals on "Phases", while the other four tracks are instrumental.

"Koan", "Trane Steps" and "Circus Circumstances" all feature frantic ensemble playing by the band, complemented by the relatively peaceful "Preview".

In 1976, Solution was coupled with Divergence as a double album, retaining the eponymous title.
