I saw Metallica on the Black album tour. My friends and I were up in the grass at Sandstone (that's what it was called then)and they came out and played for like an hour straight.
No thanks for coming, no intro's, just straight headbanging. I had to take a break a few times from the pit.
I remember my buddies and I were slamming around when one of us commented that Metallica just played 15 songs before saying:
We're Metallica, how are you all doing tonight?
Then right into another 15 songs. I don't think James said but 100 words to the crowd. Just 2 1/2 hrs of arse kicking tunes.
By far the 2nd best concert I've ever been to. The 1st being Pink Floyd.
Best Metallica warm up song is Battery, followed by Damage Inc., and finish it off with Wherever I May Roam. If you ain't pumped by the end then something is wrong with you.
