Re: CONCERTS ARE AWESOME! How many have you been to?
Matchbox 20 - Back in 1997 or 1998 (don't recall). I was in middle school at the time, and I wasn't much into the current music that kids my age were into that time so my Mom took me to this with her.
Serj Tankian & The Foo Fighters - I had went to this concert mainly for Serj, who was awesome as the opening act. Then Foo Fighters came out, and tore the house down.
Slipknot - This was 4 years ago during their "All Hope Is Gone" tour, and this was the show that got me liking them. I was aware of them before this show, but wasn't really into them until I saw them live. Amazing show, these guys have so much energy on stage and the crowd loved them. Trivium opened up for them, and they were good. Then Coheed & Cambria, who weren't very good (not a fan anyways so didn't really bother me that they weren't good).
Five Finger Death Punch - The openers were 2cents, God Forbid, and Shadows Fall, who were all pretty good. Then 5FDP came out and rocked the house. That was the most insane mosh pit I have seen, and I was right near it because the venue was small.
Rockstar Uproar Festival - Went to this in 2010 and 2011. In 2010 the headliner was Disturbed, but the opening act before them was Avenged Sevenfold and they stole the show. Other bands that were there that year were Halestorm, Hellyeah, Stone Sour, Hail to the Villain, and few others that I'm forgetting. Avenged Sevenfold headlined in 2011, so they are the only band that I have seen twice. Other bands that were there that year were Three Days Grace, Seether, Bullet for my Valentine, Black Tide, Airbourne, and The Art of Dying.
System of a Down - This was their reunion tour in 2011. Great show and they played all of my favorite songs. The opening act was Gogol Bordello, and they were quite interesting.
