B.E.F. (British Electric Foundation) are a band/ production company formed by former Human League members Martyn Ware and Ian Craig Marsh who later became Heaven 17, with lead singer Glenn Gregory.
Ware and Marsh released their first album as B.E.F. in 1980; entitled "Music For Stowaways"; consisting of instrumental electronica over eight tracks and was initially released only on cassette, inspired by the appearance of the first Sony Walkman (initially marketed in the UK as the Sony Stowaway).
There was also a vinyl release, but the versions you can hear in this stream are from the original cassette-version which is extremly rare these days (so please don't mind the background noise ).
With tracks like "The Old At Rest" or "Uptown Apocalypse", "Music For Stowaways" offers some very bizarre, experimental and interesting ambient-tracks which were blueprints or tryouts for some Heaven 17-songs and soundscapes later.
Also involved in this production was Adi Newton (Clock DVA/Anti-Group)
