Seasons In The Abyss (1990–1993)

Slayer returned to the studio with co-producer Andy Wallace in 1989, to record their fifth studio album. Following the backlash created by South of Heaven," Slayer returned to the "pounding speed of Reign in Blood"," while retaining their newfound melodic sense. Seasons in the Abyss, released on October 25, 1990, was the first Slayer album to be released under Rubin's new Def American label, as he parted ways with Def Jam owner Russell Simmons over creative differences. The album debuted at #44 on the Billboard 200, and was certified gold in 1992. The title track spawned Slayer's second music video, which was filmed in front of the Giza pyramids in Egypt prior to the Gulf War. Slayer returned as a live act in September 1990 to co-headline the European Clash of the Titans tour with Megadeth, Suicidal Tendencies, and Testament. During the sold out European leg of this tour tickets fetched up to 1,000 Deutschmark ($680 USD) on the black market. With the popularity of American thrash at its peak, the tour was extended to the US beginning in May 1991, with Megadeth, Anthrax and opening act Alice in Chains. The band released a double live album, Decade of Aggression in 1991, to celebrate ten years. The compilation debuted at #55 on the Billboard 200.

In May 1992, Lombardo quit the band due to conflicts with other members, as well as arguments over his wish to bring his wife on tour. Lombardo formed his own band Grip Inc, with Voodoocult guitarist Waldemar Sorychta, and Slayer recruited former Forbidden drummer Paul Bostaph to fill his place. Slayer made its debut appearance with Bostaph at the 1992 Monsters of Rock festival at Castle Donington. Bostaph's first studio effort was a medley of three Exploited songs, "War", "UK '82", and "Disorder", with rapper Ice T, for the Judgment Night movie soundtrack in 1993.
