Lots of metalheads know Iced Earth and also Blind Guardian but they dont know that they collaborate together on a project called DEMONS & WIZARDS, killer riffs of Jon Shaffer and powerful vocals of Hansi Kurch, they have released 2 album:
-Demons & Wizards (2000)
- Touched by the Crimson King (2005)
I highly recommend to listen to these albums, here are two songs to warm you up!
