My impressions (coming from someone who saw all these bands play at the Metroplex 20-odd years ago):
Testament's sound was utterly awful. I couldn't hear Eric Peterson at all. Maybe it was just where I was standing.
Joey Vera did a great job standing in for Frank Bello, and it was a nice surprise to hear Deathrider and Medusa.
Death Angel was the best band of the night, even though they had only a short time to play.
