Input:  South of Heaven was recorded in Los Angeles , California with Reign in Blood producer Rick Rubin . PopMatters reviewer Adrien Begrand observed that Rubin 's production shoves [ Dave ] Lombardo 's drumming right up front in the mix . Guitarist Jeff Hanneman has since said that South of Heaven was the only album the band members discussed before writing the music . Aware that they  couldn 't top Reign in Blood  , and that whatever they recorded would be  compared to that album  , he believed they  had to slow down , something Slayer had never done on albums before , or since . Guitarist Kerry King cited the need to  keep people guessing  as another reason for the musical shift .  In order to contrast the aggressive assault put forth on Reign in Blood , Slayer consciously slowed down the tempo of the album as a whole  , according to Slayer 's official biography .  They also added elements like undistorted guitars and toned @-@ down vocal styles not heard on previous albums .  King has since been critical of his performance , which he describes as his  most lackluster . King attributes this to the fact he had recently married , and moved to Phoenix , Arizona . Describing himself as  probably the odd man out at that point  , he admitted he  didn ’ t participate as much because of that .  Hanneman said :  We go through dry spells sometimes , but the good thing about having two guitar players that can write music is that you are never gonna go without . I guess at that time , Kerry was hitting a dry spell . King has also been critical of the album in general , describing it as one of his least favorite Slayer albums . He feels vocalist Tom Araya moved too far away from his regular vocal style , and  added too much singing .  Drummer Dave Lombardo has since observed :  There was fire on all the records , but it started dimming when South of Heaven came into the picture . And that 's me personally . Again , I was probably wanting something else . Judas Priest 's  Dissident Aggressor  is the only cover version to appear on a Slayer studio album . The song was chosen due to its war @-@ themed lyrics . Hanneman described the track as  more just like one of those odd songs that a lot of people didn 't know , but it was a favorite of Kerry and I , so we just picked that one . Meanwhile ,  Cleanse the Soul has been heavily criticized by King who said that he hates the track :  That 's one of the black marks in our history , in my book . I just fucking think it 's horrible . [ Laughs ] I hate the opening riff . It 's what we call a ' happy riff . ' It 's just like ' la @-@ lala @-@ la @-@ la @-@ la . ' I can 't see myself playing it , but after that , where it gets heavier , I like that section . If we ever did a medley , I 'd put part of that in there .  The Slayer boxset Soundtrack to the Apocalypse featured , along with four songs of the album , an early version of the title track , recorded at Hanneman 's home . fill in the blank  :  South of __________________ was recorded in Los Angeles , California with Reign in Blood producer Rick Rubin .
