I know this is going to make me sound very old but I remember having a few Tim Buckley albums in the 1960s, on the Elektra label.
He was part of what was loosely called "progressive music", separate from "chart" music and generally appealing to "hippies".
This was until that type of music (Pink Floyd, Genesis, Byrds, Dylan etc) became just as big as chart music.
One album from that period I still listen to is Forever Changes by a group called Love, a real classic of an album.
Here is one of the tracks from it
