I saw these guy last night not knowing what I was getting into. Fuck dude. I was hit with a wall of sound that actually physically hurt. I was up pretty close and these guys turned up the sound a little every song. During the last song the fucking tried to make our ears bleed. It was so fucking intense I don't think it can be captured on audio.
It was clear as a bell. My Brother works for L-Acoustics over here in America and word is that at the festival "Coachella" the were showing off a brand new sound system and people from all over the world were coming to check it out.
