Stratovarius is one of my favorites!
I saw them live with Timo Tolkki during the Stratovarius World Tour in 2006, and they put on such a great show! When they played "The Abyss of Your Eyes", I got so pumped up! I don't think I've ever gotten so excited at a concert before.
I got all of their autographs, and Lauri Porra and TImo Kotipelto were such nice guys.
I am also a huge fan of Jens Johansson as well. I like all of his solo projects. "The Last Viking" album (with Jens Johansson, Anders Johansson, Michael Romeo, and Goran Edman) is one of the best power metal albums I've ever heard, and right up their with "Visions" for me.
