Q:  Two songs taken from the album (  Mandatory Suicide  and  South of Heaven ) have become near constant fixtures in the band 's live setlist , notching up appearances on the following : the live DVDs Live Intrusion , War at the Warfield , Still Reigning , Soundtrack to the Apocalypse 's deluxe edition 's bonus live disc , and the live double album Decade of Aggression . Lombardo guested with Finnish cellist group Apocalyptica on a live medley of the two tracks at 1998 's Headbanger 's Heaven festival in the Netherlands . Adrien Begrand of PopMatters described  South of Heaven  as  an unorthodox set opener in theory  , noting  the song went over like a megaton bomb detonating the place : dozens of inverted crosses projected behind the high drum riser , the sinewy opening notes kicked in , followed by an overture of bass , cymbal crashes , and tom fills , leading up to the slowly building crescendo  in a concert review . Lombardo remembers listening to a live rendition of  South of Heaven  and thinking  ‘ Man ! There 's just so much groove in that song . ’ To my kids I was saying , ‘ Listen to that ! Listen to how groovy that is ! ’ And it 's heavy . A rare live version of the track featured on the JÄGERMUSIC Rarities 2004 promotional CD , given away to attendees at the Spring 2004 Jägermeister Music Tour . A live rendition of  South of Heaven  was also included on a bonus DVD which came with the group 's 2007 re @-@ release of ninth studio album Christ Illusion , shot in Vancouver , British Columbia during 2006 's Unholy Alliance tour . fill in the blank  :  Metal Maniacs asked Slayer in a 2006 interview whether they would consider playing South of Heaven .
