1. Surface De Glace 2. Target 3. Track Ii Ambient music for the end of time does not get any more authentic than this. The Structures album is a time capsule unlocked, containing previously unreleased recordings from the years 1985 to 1989. Music which meshes the extremes of "end of time foreboding" and "drifting lightness" to beguiling effect. Music which succeeds in sounding more contemporary now that it did when it was made. Its time has come. Electronic keyboards and guitars are the dominant sound sources.
