I think the "Works" version (studio) of Embryo is more reminiscent of CWTAE. A little mellower, with lyrics, but a similar spookyness.

I have a live version of Embryo done in 1971 that has a much different mood. Lots of Gilmour guitar work makes it better, IMO, more of a rocker; and it has more of an "Echoes" or "ASOS" flavor to it.

IMO the Live versions are best, but get both, people.
