Tangerine Dream https://youtu.be/73mrtLt9FDU
(They MUST have at LEAST 60 or 70 albums out and, although I still don't have all of their stuff, what I do have would take 8.5 DAYS to listen to from start to finish!!
Their founding member, Edgar Froese, just died a few weeks ago, he was at least 72 and was the only member of the band to play on every recording they ever did. He was a HUGE Beatles fan and took the name Tangerine Dream from the lyrics to, "Lucy In The Sky With Diamonds".
They did TONS of soundtrack albums in the `80's!!
This album, "Stratosfear" is their very best album!! ESPECIALLY the last song!! Although, John Peel says that "Phaedra" was their best. I'd say it's a close second. Their first album was very experimental, their next half dozen were pretty atmospheric, like this one, the next dozen were a BIT more song-centric, only one or two of them having a singer.
Most of their albums are pretty good, but the ones in the late `80's or so are a bit too song-centric. They were better in their early years when they were spacey, largely improvisational and used lots of mellotron.)
