I love Testament, and they definitely bring it live, but I agree about changing up the set, and I feel like they could even add at least two or three more songs. With a catalog such as theirs, it wouldn't hurt at all to lengthen the set a bit.
07/31 - The Iron Maidens
09/05 - Billy Joel
09/19 - Def Leppard
10/01 - Queensr˙che / Scorpions
