Well, for one band that was NOT really tight at all live was Within the Ruins. Was pretty disappointed actually. Then again, their albums are so fucking edited to hell and back......
Saw both Karnivool and Gojira at Sonisphere yesterday, both were insane. But Karnivool is the best I've ever experienced. At 2 o'clock in the afternoon. Fucking hell, what a band.
I think that video is edited though, it sounds too close to the grid to be real, also the video does not match the actual sound if I'm right (at 1:00 it is obvious when they slide in between notes while the audio does not)
Nevertheless, they are pretty tight edited or not !
