Patricia Day is the Danish upright bassist and lead singer for the rockabilly/psychobilly band, HorrorPops.
Patricia Day began her musical career performing with the Danish punk rock band Peanut Pump Gun. She met Nekromantix singer and bassist, Kim Nekroman. The two formed a band in 1996 called Horrorpops. Day is the lead singer and also plays upright bass. Day and Nekroman decided to form a band where they could experiment with many genres outside of their normal bands, and decided to start by switching instruments. Nekroman taught Day how to play an upright bass, while she taught him how to play guitar. The two began auditioning for a drummer, with Nekromantix guitarist Peter Sandorff even being a possible choice. They eventually chose Niedermeier to drum, a friend of Day's and a member of the band Strawberry Slaughterhouse, and officially started HorrorPops in 1998. After touring for a while as a trio, the band recruited Niedermeier's old bandmate, Caz the Clash, as a second guitarist.
In 2000 the group recorded a 7-song demo for use in a press kit, but it was somehow leaked to the public, and resulted in two of the group's singles, "Ghouls" and "Psychobitches outta Hell" becoming club hits in Denmark. The group spent the next few years touring Europe, until 2003, when they began recording 6 more demo tracks. During this time, Caz the Clash left the band and was replaced by another Strawberry Slaughterhouse member, Karsten. Hellcat Records, Tim Armstrong's record label, decided to sign HorrorPops based on their demos. The band was able to release a vinyl single in September 2003, and began a U.S. headlining tour.
The band's first album Hell Yeah! was released on 10 February 2004, soon after moving from Denmark to Los Angeles. The second album, Bring It On!, was released on 13 September 2005 and featured their new rhythm guitarist Geoff Kresge. The HorrorPops spent most of 2006 touring Canada, Asia, Europe, and the States, including a Warped Tour stint. Kresge left the group before the band's next album, bringing the group back to three members. Their third album, released on 5 February 2008, is titled Kiss Kiss Kill Kill. The band began a North American tour around the time the album was released.
