This is a new reissue of an album from 1973. It might not be full on progressive rock. It's clearly set in something close to proto prog, though. There are some sections that are pretty firmly set in prog rock. Some other sections wander pretty far from that position. All in all, though, this is an effective set no matter howyou label it.
