I get bored real easy. Only if the band is absolutely extraordinary will I just stand there and watch... as in, not just the playing but what they're doing on stage. One time I saw this hardcore band called Showbread... it was like they were having a collective granmol seizure. And there was this one part where all four guitarists (including the bassist) suddenly took their guitars off and started twirling them over their heads by the headstocks and missing each other's heads by mere inches... it was almost choreographed but very random and violent. Everyone was too mesmerized to move.
