After listening to the new probot album, I had the urge to throw in Ace of Spades , Orgasmatron, and Overkill. Just good fun metal/punk/rock. These three guys were such an influence on metal, and few metal fans i know ever listen to them. If anyhting they are more famous for having a cool t shirt and the ugliest singer ever, than being a groudbreaking band that did much to inspire metal.
