I saw the concert last night at Nissan Pavillion. It didn't rain, the weather was very nice, and the venue not too crowded, surprisingly. I didn't see too many drunk/high people, and the crowd seemed mostly older - 30s and 40s (I'm 46) and even older. Everything was outrageously expensive - we spent about $130 on beer and food and water. We had pretty good seats and I had binoculars too.
I didn't care for Testament, so didn't really listen to them.
Motorhead, was, well, Motorhead! Same as they always have been; one song sounds like another. They did Ace of Spades but did not do Iron Fist.
Heaven and Hell was good. Iommi's guitar was perfect. Dio has a nice voice, but ZERO stage presence and his lyrics have always sucked. I never have been a Dio fan, but it was worth it to see Iommi and Butler and Ward.
Priest was very very good. Halford didn't seem to exude the energy I always remember him having but his voice was good. He struggled a bit on Painkiller, but I don't think there's anyone else who can sing that song! He changed coats for every single song and I'd like to have some of those coats he was wearing! I bet some of them weighed 50 pounds with all the metal they had on them!
I wore earplugs so have saved my hearing - it was LOUD!
And I have come away with another great memory of a great metal concert!
