Possibly the most sonically-charged blues number Zep ever rattled through, Nobodys Fault But Mine marks one of the only two moments when Presence strays from its all out rock attack. Zep were a great believer in the light/shade approach to music, and never was that logic put to more instant, dramatic use than in this song. The pregnant pauses between riff and rhythms sound as if the song is in terminal labour. Imagine if Zeppelin had stuck to doing the blues in this punk-infused fashion throughout the 80s. It would have been sorely out of touch with what was happening with the rest of the music world, but then again, isnt that what Led Zeppelin were about anyway? How many other bands can you name in the 70s who carried the diversity that Led Zeppelin did? And how different might the 80s have been had Zeppelin ploughed on?
