I have been to a lot of concerts in my younger days. As far as musical talent Joe bonamassa is one of the best due to his absolutely killer guitar skills. I have went to oz test for like 6 years straight or so, pretty good up until 2008 when I stopped going. And Jimmy buffet is freaking amazing concerts go to also went to those for like 6 years in a row. The biggest and wildest parties I've ever seen. But Metallica and Godsmack in the round at Rosemont horizon one of the most memorable.
