Twenty Sixty Six and Then Reflections on the Future Review by Gary Hill
I've never heard of these guys before. Given the strength of this set, it's my loss. These guys occupy the proto-prog territory that came directly out of psychedelia. I'd land them more fully under the prog heading most of the time, but there is a lot of psychedelic rock in the mix. However you label this, though, this double CD reissue is exceptional.
