Ex-Flotsam and Jetsam bassist Troy Gregory replaced Kirkland for 1991's Prove You Wrong, which featured another strong single in "Unconditional," but was essentially a creative holding pattern and lost some of the band's momentum. Gregory was soon ousted and supplanted by two ex-Killing Joke and Murder Inc. members in bassist Paul Raven and keyboard player John Bechdel for 1994's Cleansing. Containing arguably their best work, the album saw a slight change of direction toward a more industrial sound, with Victor's precise riffing making way for a greater sense of groove and melody. It did little to increase the group's commercial appeal, however. Prong would disband following 1996's less inspired Rude Awakening. Parsons then went on to join British industrialists Godflesh while Victor toured with goth punks Danzig, but rumors persisted of an eventual Prong reunion.
Prong re-formed in 2000, and after releasing a live album, 100% Live, the bandmembers went back into the studio to write their first studio album in six years, 2003's Scorpio Rising. Signed to Al Jourgensen's 13th Planet label, Prong released their seventh album, Power of the Damager, in 2007. A remix album, Power of the Damn Mixxxer, followed in 2009 before the band returned three years later with Carved into Stone. Their ninth album, the thrash-heavy Ruining Lives, appeared in May of 2014. The all-covers album Songs from the Black Hole followed in 2015 and featured songs from influences like Bad Brains ("Banned in D.C."), Neil Young ("Cortez the Killer"), and Sisters of Mercy ("Vision Thing"). ~ Eduardo Rivadavia, Rovi
