I listen to most of what has been mentioned here... but two of my favorite groups were missing, so I'll give them a shout. Breaking Benjamin is a kick ass band- I was listening to them all afternoon while grading papers. Their newest CD We Are Not Alone rocks.

Second group is a more local group from Annapolis- but rock fans in MD, VA, NJ and PA ought to check them out. They are called Gold Mind Squad, and they are freaking AWESOME. The rest of the country needs to watch out, cuz they are up and coming. They opened HFS'tival this year, and have a CD out called The Plague of Popularity. Very good group- check them out.
