Jeff Hanneman [SEP] Influences and style
Hanneman's major influences included hard rock and heavy metal bands like Led Zeppelin, Iron Maiden, Judas Priest, Black Sabbath, Aerosmith and hardcore punk acts such as Wasted Youth, Minor Threat, Dead Kennedys, Black Flag, T.S.O.L., which led to Slayer's 1996 album "Undisputed Attitude". Hanneman's and King's dual guitar solos have been called "wildly chaotic," and "twisted genius". "South of Heaven" featured "more technical" guitar riffs, utilizing the aforementioned tremolo picking and down-picked notes, improving musicianship while retaining a melodic sense. Both Hanneman and King were ranked #10 in "Guitar World"'s "100 Greatest Heavy Metal Guitarists of All Time."
