I'm a big fan of two kinds of music - blues and punk. The order is interchangeable. This album hits on both sides. It's great traditional blues built on basic songs and short lyrics, but instead of being delivered on an acoustic guitar - this album grabs you by the throat and makes you listen.
I'll listen to this for the primitive and gutsy feel that is in each song. This isn't a Clapton album (thankfully) and isn't filled with tricky solos and overdubs or horns - it's guitar+drums. Period. And it works. It's what rock music should be - unpredictable and gutsy.
