In response to the question raised earlier, I don’t know if Urania ever issued this on reel tape but Omega did. You can see a copy of the tape here:
There is also an mp3 clip posted. Like the LP the Omegatape was missing several minutes of music at the beginning. A unique feature of this performance was the use of actual airplane sounds rather than just the whirring propellors.
ReDiscovery reissued this tape as part of a 20th century CD, one of the few titles that is not available as a download (due to the prohibitive costs for licensing non-PD music for download; the rates are much more reasonable for physical discs). It can be found here:
Yesterday's music in today's sound.
