Damn fine piece of vintage electronica. Warm synthesizers but I think some of the tracks are sourced from her using the Bell Labs Digital synthesizer that Don Slepian utilized(check out Sea of Bliss) nevertheless the music is warm compared to the Yamaha DX-7 pap from the 80's.
Lots of twinkling arpeggios and minimalism here ala Terry Riley as well as a hint of what my ears picked up as classical European style baroque influence. All in all a very listenable electronic music album that cannot be compared to Tomita, Synergy, Wendy Carlos.
