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 [album] 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. While firmly placed in the hard rock and heavy metal categories, Deep Purple's music frequently incorporated elements of progressive rock and blues rock, prompting Canadian journalist Martin Popoff to once call the band "a reference point of a genre in metal without categorisation." In 2000, Deep Purple were ranked number 22 on VH1's "100 Greatest Artists of Hard Rock" programme. At the 2008 World Music Awards, the band received the Legend Award. In 2011, they received the Innovator Award at the 2011 Classic Rock Awards in London. A Rolling Stone readers' poll in 2012 ranked Made in Japan the sixth best live album of all time. As part of the 40th anniversary celebrations of Machine Head (1972), Re-Machined: A Tribute to Deep Purple's Machine Head was released in 2012. This tribute album included Iron Maiden, Metallica, Steve Vai, Carlos Santana, The Flaming Lips, Black Label Society, Papa Roach vocalist Jacoby Shaddix, Chickenfoot (former Van Halen members Sammy Hagar and Michael Anthony, guitarist Joe Satriani and Chad Smith of Red Hot Chili Peppers) and the supergroup Kings of Chaos (Def Leppard vocalist Joe Elliott, Steve Stevens, and former Guns N' Roses members Duff McKagan and Matt Sorum). In 2007, Deep Purple were one of the featured artists in the fourth episode of the BBC/VH1 series Seven Ages of Rock – an episode focusing on heavy metal. In May 2019 the group received the Ivor Novello Award for International Achievement from the British Academy of Songwriters, Composers, and Authors. Rock and Roll Hall of Fame Before October 2012, Deep Purple had never been nominated for induction into the Rock and Roll Hall of Fame (though they have been eligible since 1993), but were nominated for induction in 2012 and 2013. Despite ranking second in the public's vote on the Rock Hall fans' ballot, which had over half a million votes, they were not inducted by the Rock Hall committee.
