More minimalist goodness, this time from Morton Subotnick, but a much healthier cassette this time, thank heaven! I know almost nothing about this tape except what the sleeve tells me, which is... almost nothing. Track one appears on 'Morton Subotnick - Vol. 1 Electronic Works', but I can find no trace of the second track, or of this particular cassette.
Tracklisting:
A Cloudless Sky Of Sulphur ("Realized electronically by the composer")
After the Butterfly ("Digitally recorded", featuring Mario Guarneri (Trumpet) and The Twentieth Century Players, conducted by the composer)
Sulphur/Butterfly
