Follow-up, I decided to buy Offspring tickets @ Pine Knob Sunday morning, and then ...canceled/perhaps rescheduled due to a power outage. What sucked was waiting 3 hrs, and not hearing a single note from any band on the bill to find that out.
Thankfully (next day), I had Ghost tonight, and I last saw them roughly 3 years ago. Just go see them, I first saw them with Mastodon/Opeth in 2012, and they just continue to grow. Personally, the newer music doesn't hit with me in the same way, but the production/performance is really cool now/"world class" even changing out a banner background for video screens to alter the background/settings throughout the show enhances the songs, and I get it. The entire thing has always been about "Music theater" and Tobias Forge is a master of that artform, so in that regard..I'll still continue to attend for the showmanship alone.
