progressing musically, and with better production by the well-regarded Randy Burns (also Megadeth, Possessed, Nuclear Assault, Death, Dark Angel, among others), the album featured the band's first major singles, the title track, "Betrayer" and the radio-only "Love Us or Hate Us", gaining support from the Southern California radio station KNAC, and the video for "Betrayer" receiving airplay on MTV's Headbangers Ball. This – as well as playing with bands like King Diamond, Raven, Coroner, Suicidal Tendencies, Death and Sadus – greatly expanded their popularity outside of Germany. Also in 1989, German director Thomas Schadt made a documentary about Kreator (focusing on the social aspect of heavy metal in the Ruhr Area) titled Thrash Altenessen (named after the band's hometown, a suburb of Essen). Tritze left Kreator after Extreme Aggression. In 1990, with new guitarist Frank "Blackfire" Gosdzik (also formerly of Sodom), the band released their fifth studio album Coma of Souls, again produced by Burns. The album was not quite as praised as the band's previous few albums (many felt the album was "rushed" and repetitive), but still managed sell and maintain popularity quite well, with the singles "When the Sun Burns Red" and "People of the Lie" becoming hits. Experimentation (1992–2000) The early 1990s brought a decline in the popularity of traditional thrash metal. With many other thrash bands such as Metallica, Megadeth and Anthrax changing their style by incorporating more melodic elements into their compositions, Kreator began experimenting with groove metal and industrial metal around this time. The result was Renewal, released in 1992, which featured heavy death metal and industrial influences. While reaching a newer audience, the band upset many longtime fans, accusing them of "selling out". The band experienced a decline in popularity as the result of the backlash against the album. The line-up of the band underwent significant changes too. Founding member Roberto Fioretti left the band after the recording of the album and was replaced by Andreas Herz. In 1994, Reil left as well, leaving Petrozza the sole original band member. Reil was replaced by Joe Cangelosi while Herz left the same year and was replaced by Christian Giesler. During this time "Epic Records" dropped the band from the contract making them enter into an agreement with GUN Records. The new lineup released the album Cause for Conflict the same year. The songs bore a heavy influence of such bands as Pantera and Machine
