What is the name of the song covered by monstrosity in 1999?
"Raining Blood" was covered by Tori Amos on her 2001 album Strange Little Girls. King has admitted that he thought the cover was odd: "It took me a minute and a half to find a spot in the song where I knew where she was. It's so weird. If she had never told us, we would have never known. You could have played it for us and we'd have been like, 'What's that?' Like a minute and a half through I heard a line and was like, 'I know where she's at!'". The band, however, liked the cover enough to send Slayer T-shirts to her. The song was also covered by Malevolent Creation, Chimaira, Vader, Dokaka, Reggie and the Full Effect and Killick Erik Hinds, who covered the entire album on a H'arpeggione. "Raining Blood" was also covered by the New Zealand drum and bass band Concord Dawn on their 2003 album Uprising, and by Nashville, Tennessee band Asschapel on their 7" "Satanation". A medley of "Raining Blood" and "Postmortem" appears on Body Count's 2016 album Bloodlust, preceded by a short monologue by lead singer Ice-T where he names Slayer as both a major influence on Body Count and as one of his favorite bands of all time "and always will be"; a video for Body Count's version was released in August 2017. 
In 2005, the Slayer tribute band Dead Skin Mask released an album with eight Slayer tracks, including "Angel of Death". The death metal band Monstrosity covered the song in 1999, while the track was featured on the classical band Apocalyptica's 2006 album Amplified / A Decade of Reinventing the Cello. A Slayer tribute album titled Al Sur del Abismo (Tributo Argentino a Slayer), compiled by Hurling Metal Records, featured sixteen tracks covered by Argentina metal bands, including Asinesia's version of "Angel of Death".
