Repentless is the twelfth and final studio album by American thrash metal band Slayer, released on September 11, 2015. This is the band's only album recorded without guitarist Jeff Hanneman, who died from liver cirrhosis in 2013 and was replaced by Gary Holt. It is also the first album to feature drummer Paul Bostaph since God Hates Us All (2001). Repentless is also the only album the band released on Nuclear Blast and was produced by Terry Date, replacing Rick Rubin after twenty-nine years and nine studio albums as their producer or executive producer. The six-year gap between World Painted Blood (2009) and Repentless was also the longest between two Slayer albums in their career.
