SLAYER is an American thrash metal band from Huntington Park, California, formed in 1981. The band was founded by guitarists Jeff Hanneman and Kerry King. Slayer rose to fame as one of the leaders of the American thrash metal movement with their 1986 release, Reign in Blood, which has been called "the heaviest album of all time" by Kerrang!. The band is credited as one of the "Big Four" thrash metal bands, along with Metallica, Anthrax, and Megadeth. Slayer is best known for speaking through perspective without being necessarily sympathetic to the cause of their inspiration. Slayer's musical traits involve fast tremolo picking, guitar solos, double bass drumming, and shouting vocals. The band's lyrics and album art, which cover topics such as death, deviants, genocide, insanity, Nazism, necrophilia, religion, Satanism, serial killers, suicide, and warfare have generated album bans, delays, lawsuits and strong criticism from religious groups and the general public.
