HorrorPops are a Danish punk band that formed in 1996. The band's sound is rooted in psychobilly, rockabilly, and punk rock. Band founders Patricia Day and Kim Nekroman first met when Day's now-defunct band, the punk rock group Peanut Pump Gun, opened for Nekroman's psychobilly band, Nekromantix, at a festival in Cologne, Germany in 1996. Despite both belonging to the subculture scene of Copenhagen, Denmark, the two had never met before, but they became friends over their mutual interest in alternative music. The two would eventually marry.
