Slayer is an American thrash metal band from Huntington Park, California. Formed in 1981, the group was founded by guitarists Jeff Hanneman and Kerry King. Slayer rose to fame with their 1986 release, Reign in Blood, and is credited as one of the "Big Four" thrash metal acts, along with Metallica, Megadeth and Anthrax.Slayer's musical traits involve fast tremolo picking, atonal guitar solos, double bass drumming, and shouting vocals. The band's lyrics and album art, which cover topics such as serial killers, Satanism, religion and warfare, have generated album bans, delays, lawsuits and strong criticism from religious groups and the public.Since their debut album in 1983, the band has released two live albums, one box set, six videos, two extended plays, and eleven studio albums, four of which have received gold certification in the United States. The band has received five Grammy nominations, winning two of them; one in 2007 for the song "Eyes of the Insane", and one in 2008 for the song "Final Six". They have played music festivals worldwide, including Unholy Alliance, Download and Ozzfest.
