Query: not so good

Definately not their best, but look at when it came out. This was a bad time for metal. It's still VIO-LENCE though, and if you like them, you might dig this one. However, If you think Machine Head is better, you're not really metal anyway, and probably have a nirvana collection, or a lot of that "cookie monster" crap that's called metal, and still bummed about Kurt Cobain.
