I've never heard this 'til now. I am a fan of the Temporary Secretary era McCartney tom foolery because it's really fun in the context of experimentation. I also love Neil Young's Trans record for this very reason. Any time an artist takes a chance it's worth a listen! Apparently Apple records had an experimental avant guard wing called Zapple. This imprint had two releases. John and Yoko's Unfinished Music No.2: Life with the Lions and George Harrison's Electronic Sound.
Here's George's avant record on youtube if you want to listen:
It fits in with the experimental vibes of Synergy, Larry Fast, Brian Eno, BBC Radiophonic Workshop, and Many other old school synth fun albums that i like quite a lot! Plus it was 100% Moog Modular!
There's some controversy surrounding it as well. It seems that Bernie Krause, of The Monkeys fame, actually piloted the Moog and showed George how it worked which George secretly recorded and used as part of the LP...
