Vangelis plays all instruments: exclusively synthesisers and drum machines.

Spoken-word vocals are contributed by various guest artists (Kathy Hill on "Good to See You"; Mikamo Yuko and Kimura Rieko on "Twilight" and "Red Lights"), with recorded footsteps and vocal narrative at points throughout the album by Roman Polanski and Emmanuelle Seigner.

Vangelis employs a wide range of styles, from jazz (2) and rock (3) to new age (5, 6).

Instrument patches are all synthesizer-based, but sound very convincing (trumpet on 1, guitar on 3, cello on 8).

It can also not be easily linked with his subsequent work, such as the 1492: Conquest of Paradise soundtrack.
