What are you talking about? While ACDC is fine (I guess), its music was just made-for-radio 3 minute, 30 second standard rock fare. Zeppelin was way more inspired, with a blend of both simple and complex music. Its music varies wildly from the heavily blues inspired early albums with screeching vocals on tunes such as Communication Breakdown and Since I've Been Lovin' You, to funky ethereal jams on Physical Graffiti, to its later Moroccan inspired stuff like Achilles Last Stand. Zeppelin is one of the best bands of all time. According to Rolling Stone magazine (which lists Led Zeppelin as the 14th best band of all time), "Heavy metal would not exist without Led Zeppelin, and if it did, it would suck. Led Zeppelin were more than just a band — they were the perfect combination of the most intense elements: passion and mystery and expertise." Where does Rolling Stone have ACDC in its list of top 100 artists of all time? 72nd. Not bad, but not Zeppelin.
