Album title and lyrical themes
Diabolus in Musica is a Latin term for "The Devil in Music" or tritone. Medieval musical rules did not allow this particular dissonance. According to one mythology, the interval was considered sexual and would bring out the devil; Slayer vocalist and bassist Tom Araya jokingly said that people were executed for writing and using the interval.
Araya held concern about the lyrics that King penned to "In the Name of God", voicing his opinion to guitarist Hanneman. King's viewpoint was; "It's like, 'C'mon, man, you're in Slayer. You're the antichrist — you said it yourself on the first album!' You can't draw the line like that. Whether he agrees with it or not, he didn't write it — I wrote it. So you have to say, 'Well, it's just a part of being in this band.' Now Jeff and I, we don't give a fuck. If Jeff wrote something I had a problem with, I would never even raise a fucking finger. I'd be like, 'Fuck yeah, let's do it! Gonna piss someone off? Alright!'"

Following the release of the album, the band commenced the Diabolus in Musica tour. From 1998 to 1999, Slayer toured with Sepultura, System of a Down, Fear Factory, Kilgore, Clutch, Meshuggah, and Sick of It All.
