An interesting question, sadly no idea of the answer though. I've got the 1991 Tomita "Snowflakes are Dancing" in Dolby Surround on CD released by RCA Victor/BMG Classics.
the first Dolby Surround music CDs came out on RCA Victor in l989. An initial release was "The Home Video Album" [Victor 60354-2RC].
