Best album of the 90's, bar none. If you have one shred of political angst in you or you simply enjoying rocking out, there's no reason why this wouldn't be in your collection. Every song is a 10, Tom Morello(and his magic tricks) provide continuous ear candy, along with the deep, timely bass of Timmy C. and the heartfelt pounding of Brad Wilk on the skins. Oh, did I mention the intense, soul-digging vocals of Mr. Zack? The guy is amazing. I could go on, but you get the idea!
