In a word... amazing.
All of the bands were great, except Archetype, IMO (and I missed seeing Katagory V, for the third time in a row

).
Morgana Lefay -- for me, the highlight of the fest -- was beyond perfect. I'm sure many of you have noticed that, often, when a very aggressive vocalist performs live, he tends to hold back, so as not to damage his voice. Not Charles. Not only did he sound as amazing live as he does on CD, but he actually sounded even MORE aggressive in the live setting. Also, I couldn't have picked the setlist any better, except for the fact that they didn't play any ballads. I would have loved to hear "Victim of the Inquisition" or "The Mirror".
Imagika - That singer needs to go
LOL... Norman is an awesome vocalist, even if he's not as melodic as you'd probably like (which is probably the case, considering that you mentioned not liking Silencer either). The former Imagika vocalist... now, HE was a stinker, LOL... the music on the first three cds is great, but let's just say that I wouldn't mind seeing some re-recordings come out.
Ion Vein - One of the best sets I've ever seen out of the guy. I'm fortuante to be in a town with such an amazing band.
Twelfth Gate - Again another great set, them and Ion Vein just keep gettin better and better. Also a Chicago band, love having these guys local.
I miss getting to see these two bands play on a regular basis.
Tad Morose was awesome, but Urban is going the wrong way! (Only a select few of you will understand this reference.) "A Mended Rhyme" was the highlight of their set for me, since Charles didn't end up getting on stage with Urban for "Matters of the Dark". (Peter filled in, and was awesome, but we were all psyched to see Charles, so it's hard not to be dissapointed.)
Urban Breed had at least two clones of himself walking around during Powerfest. I believe these were the same clones which were at ProgPower last year, although I didn't get to check the serial numbers. During Tad Morose's set, I half expected to turn around and see Urban watching himself from the audience.
Everything, and everyone, was a lot of fun this weekend. I can't wait until next year!
