Angel of Death (Slayer song) [SEP] Composition and origins
Slayer guitarist Jeff Hanneman wrote "Angel of Death" after reading books about Nazi physician Josef Mengele while on tour with the band. He said that he remembered "stopping someplace where I bought two books on Mengele. I thought, 'This has gotta be some sick shit.' So when it came time to do the record, that stuff was still in my head—that's where the lyrics to 'Angel of Death' came from." The lyrics are written both from Mengele's point of view and from that of a detached observer condemning his actions. They detail Mengele's surgical experiments on patients at the Auschwitz concentration camp during World War II.
