"On the Shore" by the British psychedelic folk-rock group "Trees" is interesting as is the classic cover art by Hipgnosis (circa 1970). This album is also out-of-print but some vinyl copies are/were available at Acoustic Sounds.
I have an enduring weakness for "The Loading Zone" (available originally as an RCA vinyl pressing of dubious sonic merit: out-of-print now), the "house band" at the Fillmore. Linda Tillery (now a gospel singer) could really belt out the cover songs.
