for me also Nolan & Wakeman - The Hound Of the Baskervilles, and definately a favourite even surpassing Jabberwocky (and thats saying something!)
other purchases since late January:
Dream Theater - Six Degrees Of Inner Turbulence (another favourite, up there with Scenes From a Memory and Images & Words and Awake
DT kicks butt)
The Lord Of the Rings Soundtrack (wow, definately a favourite!)
Camel - Nude (these guys are great! thanks to whoever recommmended them!)
Michelle Young - Marked For Madness (very odd album, loads of atmosphere)
Diana Krall - Only Trust Your Heart (love that voice!)
Thelonious Monk - Straight No Chaser (I'm still catching up on the old must haves, and this is very good stuff)
there's a lot of absolutely fantastic stuff coming up next month that all you non-proggers are gonna miss out on, but hey, not my problem
think Arena, think Pendragon, Ayreon even. I might also be (99% sure, but finances might fail) picking up Pain Of Salvation - The Perfect Element part 1, and something by Treshold, probably their latest (forgot the name, the one with the floating rock-with-city on the cover).
