I bought the CD after seeing the video for 'Love Train' on TV late one night. Their shit is awesome.
But whoever's been describing the music to you needs an HCl enema. Wolfmother's sound is akin to late 60's/early 70's power rock. Get your hands on some Led Zeppelin, Jimi Hendrix Experience, Black Sabbath, Mountain, early Rush, Deep Purple or Cream and you'll see what I mean.
Anyone interested should check out check out Wolfmother's Web Page for band info and to hear some tracks.
