Greater Than One, (also known as GTO, John + Julie, Tricky Disco and Technohead) - Lay Your Penis Down.
This was their first release and came in a small cardboard box, tied with string and sealed with wax.
Inside the box, apart from the cassette, were all manner of strange articles inside envelopes entitled 'Secrets', 'Faith', 'Motherfucker', 'Blood', 'Energy', and 'Genital' amongst others. You'll get the idea from the photo I've enclosed with the audio.
A strange composition - if you like Coil and C93 you'll probably like it.
Even stranger to think that 10 years later they were also to be responsible for the awful, happy hardcore floor filler 'I Want to be a Hippy'
