Does ELOY count? I'm a big fan of their 70's stuff.
when many of these bands where unknown to most of the world and while "Dark Side of the Moon" was a Hit, ELOYS "Wings Of Vision" was one of the No.1 songs in psychedelic German rock college radio, even out selling Floyd's "Dark Side" in Germany. https://www.youtube.com/watch?v=RGqJBeMAR9o
AMON DUUL 2
But the band of all bands IMHO was AMON DUUL 11
They drew upon Fritz Lang, Kubrick, Da Vinci and Dali with amazing grace, their last hit song was only about five years ago, they still do grateful dead like tours as of last year 2018
These are artist's artist. An opera singer, a violinist, three organist, two percussionist, banjo, saxophones, and two guitars and moogs every where next to mellotrons.
with titles like-
"Viva Le Trance"
"First National Church Of Marilyn Monroe"
"Harvest in Babylon"
these were poets, I almost never saw a band put so much melody and thunder in a single song as "Metropolis"
Always promoting, monogamy, patience, the art of being a real friend, sacred respect for women,
and in the middle of a explosion of Chain saw electronic rock theme,,,, go so melodic it almost was a mirical,
their art was at once feminine, mystic and Shakespeare.
And in songs like "Loosey Girls" the singer would cry for the lonely lost women of the world.
"Morning Excuse" is about irresponsible women, I have never heard a "Sound" like this song makes.https://www.youtube.com/watch?v=ChzqIyKfLjQhttps://www.youtube.com/watch?v=RbIw2HZRnF4https://www.youtube.com/watch?v=ol0U4dDScrE
