I definately agree...to me Wolfmother sounds like a cross between Led Zeppelin
(vocally speaking, and the fantasy-like lyrrics. they don't sound like Zeppelin to me otherwise.), and Black Sabbath. Those riffs just scream Tony Iommi
to me. They sound quite original to me though...there's something else there I haven't been able to put my finger on it yet. I loved their debut album. I hope they can follow up with something that's at least worthy to succeed their debut.
