Why aren't I owning this thread already, Ermz? WHY?
Ok, you may know some of these already so bare with me. These range from dense/ heavy to lighter mixes, so you should cover the work you need to do. Anything with an *** next to I'd also recommend musically for you
Rhaopsody of fire - The frozen tears of angels. They also have a new one but I haven't heard it yet. You will need some of these if/ when you work with Winterstorm haha
***Circus Maximus - Isolate. One of my top albums next to In search of truth and lots of variety between synths and orchestra's.
Kamelot - Epica and Black Halo
Blind Guardian - A night at the opera (got slammed, and still does, for having too much orchastration. I love it), Nightfall on middle Earth (many fan's favourite of theirs), At the Edge of time (newest).
Eyefear - Basically any of them. The Unseen was mixed by Borgren IIRC.
Iced Earth - the crucible of man. Somethign a little heavier.
Pagan's Mind - God's Equation and Enigmatic Calling. Both of these are a bit more progy, can be light on the orchestration most of the time.
Pyramaze - Legend of the bone carver
Serenity - Fallen Sanctuary
That's all I can think of at the moment
