Slooooowwwww buildup, and the intro doesn't really blend into the main body of the song. But apart from that, its really sick! Awesome! Production wise its really good, and I luv your sounds and samples. Not much to critisize here, except that the intro and breaks are too different from the faster parts of the track IMHO. Well done!
BTW: I'm from the DC area as well (Silver Spring). Interested to hook up?
