Interesting...
Last year went I went to PP(my first PP) I only knew of Stratovarius, Therion, and Angra. The rest of the bands to me were totally unknown, but as the concert approached, I kept listening to the bands that I wasn't familiar with and actually found that they are really good.
Thus, now reaching my point, I trust Glenn in his choice of bands every year, even if i haven't a darn clue to who they are, because now i tell everybody this..if they are at progpower, then they are going to be
amazing.
This year, im going to PP with friends of mine that don't like some of the bands on the roster, but i keep telling them, "when you see them live at progpower, on thier top notch performance level, you will definitly like them".
and that, is what is amazing about progpower,
quality of the music
