Only saw them once and the was for The Incident tour.
SW was pretty pissed because there was a lot of technically problems, like he broke a string on the first note of the very first song, and then there was weird feedback and cutting in and out with the bass, and then he was given a guitar and the capo was in the wrong spot so he's stops the song and is like "wow, this guitar is completely out of tune"
So because of all that, it was hard to tell if the tension was just from the technical problems though. The Incident song live was start and stop, and disjointed due to said technical problems so it was a chore honestly, but the 2nd half of the concert was fucking incredible. Seeing Anesthetize live was one of my all time greatest concert experiences.
