Zepp... you sure you arnt confusing cockyness with energy?
I mean if some dude tried telling me off after an awsome show,I would be a total dick and be like "f*ck you,I just played in front of 600 people you f*ckin loser" and proceed to kick that crap out of him with my friends who I assume would also be on an energy trip.I would also be act like a stud with ladies for the night/next morning.
hmmmm...mabey it would be a mix of both.
All I know is concert energy is unlike any other,in that you feel on top of everything(unless your getting stomped in a pit).
Later! \m/
Try once,fail twice...
