The latest episode of the Cassette Culture podcast focuses on Alien Brains (who were active between 1979 - '85.)
Members included (founder) Nigel Jacklin, and various occasional members, including David Jackman (Organum), Philip Sanderson (Storm Bugs), Richard Rupenus (TNB), Lionel Jarlan (Ptose), Truus de Groot (Plus Instruments), Dominic Guerin (SPK), and others.
'Even if Alien Brains had never existed, Nigel Jacklin would have claimed himself a place in Industrial music history. As a schoolboy at Oundle School, the young Jacklin convinced his music teacher to book Throbbing Gristle to play the school auditorium in March 1980, a performance that sparked a stage invasion and the amusing TG video Live At Oundle School. At the time of that TG concert, Alien Brains were already a year into operations, a useful reminder that a good proportion of the early work of the Industrial and cassette culture pioneers was undertaken while barely out of short trousers...'

The next episode focuses on the Industrial Records Tapes Received list (basically all the 'demos' submitted to Industrial Records), which appeared in TG's 'Industrial News' magazine circa 1978 - '80.
Most of those who submitted a demo to Industrial Records quickly disappeared without trace. However, some (including Cabaret Voltaire, Leather Nun, and SPK, among others) went on to achieve varying degrees of commercial success.
