Pantera revolutionized the sound and the approach to heavy metal. It's been regurgitated. Once you up the production on a product and not just the playing but the actual production, then it's going to up the ante.
I like Jay-Z, 50 Cent and Common. But I like the underground stuff like Young Jeezy, Black Rob and Shine. I also love heavy metal like Slipknot and Pantera, It's very intense stuff.
