Deep Purple are cited as one of the pioneers of hard rock and heavy metal, along with Led Zeppelin and Black Sabbath. The BBC states they “made up the ‘unholy trinity’ of British hard rock and heavy metal during the genre's 1970s golden age.” The group have influenced a number of rock and metal bands including Metallica, Judas Priest, Queen, Aerosmith, Van Halen, Alice in Chains, Pantera, Bon Jovi, Europe, Rush, Motörhead, and many new wave of British heavy metal bands such as Iron Maiden, and Def Leppard. Iron Maiden's bassist and primary songwriter, Steve Harris, states that his band's "heaviness" was inspired by "Black Sabbath and Deep Purple with a bit of Zeppelin thrown in." Van Halen founder Eddie Van Halen named “Burn” one of his favourite ever guitar riffs. Queen guitarist Brian May referred to Ritchie Blackmore as "a trail blazer and technically incredible — unpredictable in every possible way...you never knew what you were gonna see when you went to see Purple". Metallica drummer Lars Ulrich states, "When I was nine years old it was all about Deep Purple. My all time favourite is still ""Made in Japan"". The band's 1974 album "Stormbringer" was the first record owned by Till Lindemann, vocalist of German Neue Deutsche Härte band Rammstein.
