It is not always easy to be a rockstar ! During a show, Joe Perry (Aerosmith' guitarist) received Steven Tyler's microphone in the head (at 0'09'' you can hear the hit in the mic). Then the guitarist was knock out (you can hear that the strings vibrating itselves) and he leave the stage checking if there is some blood on his head. Joe Perry was so angry that he throw his guitar out of the stage...
