I have not agreed with everything SW has done either... but he has literally put out numerous hours of material I absolutely adore.
Basically all of PT's albums, I love; especially the last 4. The Incident being their potential last album ever is one of my favorites.
No-Man has so many great songs, and some albums I love from front to back.
I'm not a huge fan of his solo career (Raven is pretty good), or Storm Corrosion (though I have to give it another listen).
The 3 Opeth albums he worked on are golden.
Anathema's We're Here is one of my favorites, too, and the production is somewhat responsible.
Blackfield albums are solid.
Am I the only one who thought Circus Maximus - Nine was a solid album? I just really, really like it.
To-Mera - Exile was also pretty great.
These are more standard prog fare, but done well.
Dark Sun's Orange is very authentic sounding, and I feel you guys should check it out.
