Suicide Silence was absolutely godawful. I don't understand the 8/10. The sound was so bad. Straight Line Stitch was terrible as well. Machine Head was by far the best of the bands on the outdoor stages. All Shall Perish was good, some guy got taken out on a stretcher during their set.
You should have stayed for Godsmack man. I wasn't a big fan but that was one of the sickest shows I've seen. They were having so much fun with the crowd. Then Disturbed sucked compared to them so I left shortly after.
