i enjoyed the hell out of korn. they played like 4 songs off their first album and only 2 new songs....everything else they played was from their self titled all the way to issues with 1 untouchables song thrown in. im glad they played their older stuff and not any of the newer trash they released.
as for an encore....only place ive ever seen a headliner come back out (after crowd urging) are the smaller venues. i dont think ive ever seen ''one more song'' at the larger festival venues. especially when theyre on a strict time schedule
