What was the best concert you have ever been to?

Have you ever been to a concert of a band you kind of idolize, and did they live up to your expectations?

I just went to a concert last night that was probably the best concert experiences I've ever had. Now, Now is one of my favorite bands, and it was such an interesting experience seeing a band I've idolized live. Their performance was awesome, and the two bands that came before them (Anakin, and The Lonely Forest) were also very enjoyable.

I've also been to a Norma Jean show where one of my good friends' bands played in the concert with them which was a lot of fun despite not really enjoying most Hardcore/Metal music.
