Budgie’s debut album opens with “Guts”, boasting a riff worthy of Sabbath, before exploring a wide range of heavy rock permutations. Although the two short acoustic numbers (A2 and B3) are as strong as any of the songs here (as opposed to the filler used by certain other bands), Budgie is an exercise in prowling electric exhilaration above all else, and remains one of the few classic releases of British heavy rock. Budgie – they could have ruled the world, if only they chose a proper name.
