Task: Question Generation
Input (English): Passage: In late 1987, Slayer returned to the studio to record their fourth studio album. To contrast the speed of Reign in Blood, the band consciously decided to slow down the tempos, and incorporate more melodic singing. According to Hanneman, "We knew we couldn't top Reign in Blood, so we had to slow down. We knew whatever we did was gonna be compared to that album, and I remember we actually discussed slowing down. It was weird—we've never done that on an album, before or since."Released in July 1988, South of Heaven received mixed responses from both fans and critics, although it was Slayer's most commercially successful release at the time, debuting at number 57 on the Billboard 200, and their second album to receive gold certification in the United States. Press response to the album was mixed, with AllMusic citing the album as "disturbing and powerful", and Kim Nelly of Rolling Stone calling it "genuinely offensive satanic drivel". King said "that album was my most lackluster performance", although Araya called it a "late bloomer" which eventually grew on people.Slayer returned to the studio in spring 1990 with co-producer Andy Wallace to record its 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 had parted ways with Def Jam owner Russell Simmons over creative differences. The album debuted at number 44 on the Billboard 200, and was certified gold in 1992. The album spawned Slayer's first music video for the album's title track, which was filmed in front of the Giza pyramids in Egypt.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 had prices skyrocket 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 since their formation. The compilation debuted at number 55 on the Billboard 200.In May 1992, Lombardo left the band due to conflicts with the other members, as well as his desire to be off tour for the birth of his first child. Lombardo formed his own band Grip Inc., with Voodoocult guitarist Waldemar Sorychta, and Slayer recruited former Forbidden drummer Paul Bostaph to fill in the drummer position. 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.
