Smoke and Fire
...the night calls...
You MUST listen to Pain of Salvation first of all, of course. And try "The Window Purpose" by Wolverine (prog metal with some death metal influence - ). As for Rhapsody, try any of the first 3 (Legendary Tales, Symphony of Enchanted lands, Dawn of Victory) as the others are just repetitions (but Luca Turilli's King of the Nordic Twilight is nice, too). I also really love Nightwish and Tool, but I guess you know them already, don't you? Did I mention Star One (with Russell!)? And, if you like melodic death metal, Dark Tranquillity's "The Gallery" and "Damage Done" are great . But that's a whole different kind of music...
