In your opinion, what makes a great live performance?
Okay, so i was thinking to myself today, what makes a great live performance. My 2 favorite band's (avenged sevenfold, bullet for my valentine) live performances are considered terrible (from what i've seen others say within forums, not just this one) HOWEVER, i have seen both in concert, and because i enjoy listening to the music more than just going around acting crazy as hell in the mosh pit, i thought they sounded great, and the lights and pyrotechnics were stellar. So I want to ask you, the people of these forums, what in your opinion makes a great live performance.
