Def Leppard are an English rock band who have been active since 1977 and sold over 100 million records worldwide as of July 2014. They are one of only five rock bands with two original studio albums selling over 10 million copies in the U.S., those albums being Pyromania (1983) and Hysteria (1987). The latter ranks as one of the highest selling albums of all time, with over 20 million copies sold worldwide.
In 2002, Daron and Shavo guested on a documentary aired by VH1 about the Pyromania album to talk about the influence it had on them, with Shavo admitting that "Rock of Ages" was his favourite song of all time when he was young, also saying, "I always have a copy of [Pyromania] in my collection".
In an interview Daron did for Total Guitar magazine, when talking about his desire to be learn to play drums before picking up the guitar, he admits that because drums would have bothered the neighbours, he "used to bang on pots and pans instead. I could pretty much play the whole of Def Leppard's Pyromania on those".
