I bought this on the strength of "Prehistoric Dog". There are some great moments on the record, and I enjoy that most of the heaviness is delivered by song writing attitude as opposed to just how distorted the guitar sound was. Production values are a bit hit and miss, but given the nature of the record this doesn't matter that much.
Anything by Red Fang is amazing. Saw these guys recently live and they are AWESOME. Their albums are awesome too. In my opinion, best new stoner rock/ metal band around. Can't wait to hear their next album!
