Bret Easton Ellis’ career-defining novel turned Christian Bale’s career-making film American Psycho was recently adapted into a series of comic books from Sumerian, and later this month a graphic novel will collect all five issues. Music is quite an important component of both the novel and the film, so I suppose it makes sense that the comic books would get a soundtrack. Back in May, Puscifer shared an original song for it called “The Algorithm,” and today the unlikely pairing of Ice Nine Kills and Reel Big Fish shared a cover of Katrina And The Waves’ “Walking On Sunshine.”
