Very cool list. I'm surprised you didn't count opening acts also. Cynic opening for meshuggah and Burst opening for Gojira in my case took those shows to a much higher level.
This way makes a better list but I'm all about the whole concert experience. Or what I remember of it... hahaha
7/30 - Offspring
8/4 - Soundgarden & NIN
9/27 - Clutch
10/24 - Judas Priest & Steel Panther
