Flower Kings. Roine Stolt is good guitarist, but an awful singer and lyricist. His English also needs some serious work.
Spock's Beard & Kansas. US Radio Rock in Prog's clothing.
Rush when they were doing Prog. Once Geddy stopped screeching and they stuck to standard song structures, they sure got a lot better (Power Windows and Counterparts are two faves). However, 2112 may be one of the most abysmal albums ever.
Marillion, other than for nostalgic reasons. I still occasionally listen to the first two albums, but I hated Misplaced Childhood even when it came out (not least because IQ's flawed, yet totally superior The Wake was released at about the same time). I remember almost being smacked by Fish when I interviewed him and asked why they called a couple of Pop songs sellotaped together "one song".
Anything Italian, except Goblin.
