Last time i saw A7X was at taste of chaos. They were pretty dead on which was sick. It was also on st. patricks day so they picked people out of the crowd to come up and take shots of jameson with them, then let them stay on the side of the stage for the rest of the show.
Yep, lots of people still listen to Avenged Sevenfold. They recently headlined the Taste of Chaos, sold out a few dates, and really kicked ass when I saw them @ TOC. Pretty good band if I do say so myself.
