OK, that's cool. If they released every title from the 70's, I would buy them all. Especially....these...The next Styx Hybrid Stereo SACD from Audio Fidelity will be Kilroy Was Here.
Now "in the works" according to Marshall at AF.
Equinox (1975)
Crystal Ball (1976)
The Grand Illusion (1977)
I would also add in Cornerstone from 1981 I think it was.
