Hound Dog Taylor and the House Rockers prove that you do not need to be  great musicans to be a great blues players.  Blues is as much an emotion as it is a music style and the great play the blues with soul.  You will not be confusing Hound Dog with Robert Cray or Eric Clapton who are both better technically, but lack the raw soul needed to be great at the blues.  The Dog brings it as raw as anyone and that is what makes this is a great blues album. The rawness of this album it may not be as accessible for everyone. Would only suggest for folks already deep in the blues.  If you are looking for some great slide guitar that is a little more refined abd accessibile check out Lil' Ed and the Imperials.
