This was my sixth PPUSA fest (actually 5 1/2 since I only attended the Saturday show in 2013, back when you could get single-day tickets), and they keep getting better and better.
In brief, here are the highlights, IMO:
Gloryhammer (Wednesday): Incredibly fun cheesey Euro power metal that didn't take itself too seriously
Doro (Thursday): Good old-school metal, although from where I was sitting the guitars seemed buried in the mix
Angra (Thursday): Very fine set with their new album Omni played in its entirety. The highlight was when Doro joined them for a song
Redemption (Friday): Amazing on all levels. Yes, Tom was a bit tentative early on, but they made me a fan when I knew almost nothing about them going in.
Sons of Apollo (Friday): As you would expect with an MP project, this was outstanding, as he delivered a killer set for the second PPUSA in a row. The only disappointing thing was that they didn't really do anything special for the festival, but instead played their standard tour setlist, which they had already done when they played Atlanta in February
Vuur: Annika is an amazing vocalist and one of the festival's highlights
Alestorm: Pure goofy fun with a shark and a duck and plenty of cosplayers in the audience. KILL THE DUCK!!! IMO the best act of the weekend
Tarja: Amazing live singer, but I got distracted by the keyboarist's ongoing issues with the sound, as well as Tarja's outfit where it looked like she was always about to fall out of the top.
In addition to the great music the festival is known for the community spirit, with autograph sessions for nearly all the bands. I didn't go to every single session particularly SOA and Tarja whom had very long lines. But the bands were very gracious and willing to talk for the brief time they had before we moved on.
As for next year, it looks to be another stellar lineup, especially Saturday with Jag Panzer, Threshold and Demons & Wizards. ANd there are some interesting bands I'm not that familiar with now, including Seventh Wonder (whom I saw at the 2014 iteration) and Caligula's Horse.
