Timo Tolkki's Avalon (also known simply as Avalon) is a metal opera project created by Timo Tolkki (formerly of Stratovarius, Revolution Renaissance and Symfonia) in 2013.
According to Tolkki "I find the Metal Opera concept fascinating and logical to me at this point of my career. I love classical music and just like in Classical Opera, in the Metal Opera you can also create stories and have almost limitless possibilities musically".
