There's no denying Australian heavy rock trio Wolfmother has been raised on rock – specifically, raised on '70s rock. Problem is, from all appearances on their eponymous debut, they made their journey into the past via the twin gateway drugs of the White Stripes and Queens of the Stone Age, and once they dug back to the original Zeppelin and Sabbath texts (stopping along the way for some Soundgarden discs and maybe, for lyrical inspiration, Yes and Rush), they indulged so much it screwed with their sense of aesthetics.
