Progpower USA XV was my first, and Stratovarius headlined my very first day at the festival. Little did I know at the time, but I was already hooked on PPUSA. They played Visions in its entirety, but back then they sort of dropped the news they were playing Visions on Glenn only a few days before they were to perform. That night was pure magic.
Per Facebook Christmas Day post: "Day 2 tickets (Darkwater, Northtale, The Ocean, Pain of Salvation, Stratovarius) will go on sale Saturday, January 11."
