I love Odyssey, Nightingale, most of his Edge of Sanity stuff, Bloodbath, the tracks he sang for Therion, the covers he's done, Pan-thy-monium, some of the Godsend stuff... If you haven't guessed, I'm a fan.
I haven't heard Subway Mirror or Route 9, but I don't particularly like the Unicorn I've picked up so far. Still, people on the Dan Swano board are raving about all three projects.
What I really need to do next is get me some of the Diabolical Masquerade stuff.
