I wouldn't say no one has heard of the bands I'm going to post, but none of my friends had before I foisted their music upon them:
Soft Machine Caravan Camel Isotope Ian Carr's Nucleus Egg Hatfield and the North National Health Gilgamesh Arzachel Hugh Hopper Kevin Ayers Robert Wyatt
a lot of these are in the same vein of bands from the Canterbury scene of the late ‘60s and early ’70s, though the last 3 had extensive careers that spanned far past their original bands.
Endgames - UK Band. The Frozen Autumn - Italian Band. Delays - UK Band. Anekdoten - Swedish Band. I'm sure there are lots more! PS. I remember The Mood from the 80's too, great band.
Endgames never got the recognition they truly deserved softcell62. I think they had a hit in Germany but that's about it. Funnily enough a B-Side remix of Ecstasy became a really big club hit & the track has been sampled by other artists, so in some small way they achieved some form of success. Great band all the same & never tire of listening to them.
