Use the internet, boner. Not only ignorant, but stupid.
From Wikipedia:
Deep Purple are cited, along with Led Zeppelin and Black Sabbath, as pioneers of hard rock and heavy metal.[3][5] The group have influenced a number of rock bands, including Metallica,[92] Queen,[93] Aerosmith,[94] Van Halen,[95] Alice in Chains,[96] Pantera,[97] Bon Jovi,[98] Rush,[99] Motörhead,[100] as well as many New Wave of British Heavy Metal bands such as Iron Maiden,[101] Judas Priest,[102] and Def Leppard.[103] Iron Maiden's bassist and primary songwriter, Steve Harris, states that the band's "heaviness" was inspired by "Black Sabbath and Deep Purple with a bit of Zeppelin thrown in."[104] Lead vocalist of Def Leppard, Joe Elliot, has stated, "In 1971, there were only three bands that mattered, Led Zeppelin, Black Sabbath, and Deep Purple."[4] In 2000, Deep Purple were ranked number 22 on VH1's "100 Greatest Artists of Hard Rock" programme.[105] In 2011, they received the Innovator Award at the 2011 Classic Rock Awards in London.[16]
