Both sets were amazing, but I loved the subtlety and choices of covers of Vanden Plas. Plus Andy Kuntz, he is quite the frontman and the vocalist. I could have stayed for 3 hours watching these guys play acoustic songs...
I am admittedly biased because I am much more of a fan of VP than Evergrey, but I was absolutely floored by the VP acoustic show. In my wildest dreams, I never thought I would hear Mr. Bojangles at a PPUSA show, much less absolutely love it. That was a magical performance and was the highlight of the fest for me.
I really regret missing the VP acoustic set! I was kept awake all night by teenagers and what passes for a young adult!!!!! Next year I will have my OWN room!
I love acoustic sets so both were fantastic for me....though I have to say VP blew me away, and along with the Therion set, has to be one of the best sets I have yet to see all time let alone at Prog Power and that says a lot as I have seen quite a few phenomenal sets in my time.
