This is the Flux "In Flux" cassette from 1987.
The guys involved in the recording were - KL Guthrie - M Kane & E McDougall.
There are 10 tracks in total, and the one here below for you to sample is a number called "So Clear, It's So Clear", a short trippy ambient offering. This is the mellowest track on the cassette compared to the rest of the material, which is rather abrasive, but thought I'd ease you gently into their sound with this piece first, and I'll put one of their contrasting tracks up sometime later.
Although the track here was recorded in '87, it does hark back to the mid '70's in an Eno/Krautrock kind of way.
Thanx to Mike.
