I have been to a number of concerts in my life so far, and they have all been great experiences.

I love a good mosh pit, but a wall of death is even better.

And unless you're bleeding from the ears, the music isn't too loud.

Oh yeah, list of bands I have seen live:
Slayer
Lamb of God
Mastodon
Amon Amarth
Children of Bodom
Thine Eyes Bleed
Job for a Cowboy
Suicide Silence
God Forbid
It Dies Today
Avenged Sevenfold
Bleeding Through
30 Seconds to Mars (-_-)
And more...
