The next band will be...

Symphony X would be great!
Together with Circus Maximus, Shadow Gallery and Riverside - That would be the best festival for me - ever!
 
Don't know if Borknagar is a band that would fit at ProgPower?

I'm listening their work for the first time at the moment and this is actually very very very interesting...
 
CULPRIT!?!

They are together again, making plans for new stuff and want to come to Europe for some festivals!

Although not realy progmetal, but one of my alltime favorites. Very powerful and pretty progressive US Metal.
 
Bring on FREAK KITCHEN!!!!

They'll be touring in Europe by that time.....
Keep my fingers crossed they come to Holland!
 
Well, maybe GAZPACHO as a headliner would be nice ... Just listened to Tick Tock and A Night At Loreley and it's awesome!
 
I have to agree with Redemption, ofcourse, but I personally wasn't impressed with BigElf when I saw them perform as Dream Theater's support a while back.

The 3 of us who saw Bigelf on their own tour were heavily impresssed!
And I think having a real Mellotron on stage instead of a sample would just be fair at a PROGpower festival. ;)
