Saw JP live in 2018. Painkiller was the encore song and hol-ee crap. Glen Tipton came out, (he wasn't on during the rest of the show, the other two newer guitarists were though. They're beasts too though)
Painkiller with 3 guitars is even better than Painkiller with 2 guitars xD and Rob's still got the vox too, doesn't even sound like he's aged. Actually added a death growl at the end of the final shriek.
This album is really good by the way. It's basically Painkiller II tons of great songs on it.
