I'm in on that
Loved all of them, especially the 1st (PoS), but cost and taste has never found me going back. I still check out the roster every year and follow Glenn/PPUSA on Social Media though.
Taste as in your own taste or the festival's taste has changed?
probably more to do with my own, but in a nutshell: when PPUSA started, they had a lot of Prog Metal bands I wanted to see, and even some Power Metal. Power Metal as-a-whole has never been a genre I've loved, but I find some exceptions.
But there are more artists that play the festival now, even among the Prog Metal acts, that I'm either not into or don't know.
But there are some recent years with groups I'd enjoy seeing, but the cost (beyond budget limits, I would have a hard time justifying it to my wife given she would have no interest whatsoever). But I also find the counter being to just use what money I have on seeing local shows, or in the rare occasion taking a trip with my wife, for something we'd both enjoy (more her primary taste, that I also enjoy).
We'd all like to hold our own festival (hold, not RUN I'm sure), and I would say back in 2001, 2002, 2004, the Prog Metal bands that played or might play PP I loved, but the last decade or more, I would say my primary taste is not with the Prog Metal, as it was back then. Is it because Prog Metal was better back then? maybe. Or perhaps I just am not into traditional sounding Prog Metal, even if so many others that attend PPUSA every year are.
