it turns pretty bluesy, pretty fast. If I want blues rock, I'll go with LZ, as mentioned.
Maybe I'm looking for something that doesn't exist, but I want lots more of that sound from track 1 on the first album.
Also, War Pigs is completely awesome. Different sound, but same idea: it got this creepy feel, and it doesn't sound like anything else from the time period ( which was mostly blues inspired rock).
