I have the Sunspots reissue of the Silva Seasons LP, recorded by ORTF, because the original pressing is so poor. That CD set sounds really good.
The remaining Actuels, of which I have uh - all of them, vary widely in recording quality as well as pressing. The ones done at Studio Saravah I remember being pretty good, like the Don Cherrys and (I think) the Dewey Redman.
