I love 2112, but Hemispheres is the one that doesn't get enough credit imo.
Totally agree here. Hemispheres is a masterpiece. La Villa Strangiato and The Trees are two of my all-time favorites.
Also, with regards to 2112, they need to just do what it takes to get Steven Wilson doing all of their remasters. The 5.1 mix they put out was a total swing and miss and Steven could have put that album completely over the top. Listen to the 5.1 mix of In the Court of the Crimson King (with crappy old magnetic tapes no less) if you have any doubt.
