As much as I love Zak, Jon is Savatage. There is that time, however, between Criss's death and the monstrosity that is TSO became what is that Savatage was something different. It was a fragile teenage trying to find itself. The result were some of the best prog-metal albums to ever grace the world. Handful of Rain, Dead Winter Dead and Wake of Magellan, easily some of the best out there.
So, here are some good Zak videos on YouTube for all your loving affection.
