There have been at least two Party Girls:

LOU: A rock band with hardcore/punk pedigree playing around Louisville in the late 90s/early 00s. They released a 7" with The Mack and had a song on the 'Redneck Buddhas' comp, as well as some home recordings floating around.

PDX: Started as an electronic-heavy duo by Gabe Castro and Ryan Wolf, Party Girls is now a full 4-piece from Portland OR. With elements of heavy, electro and old style screamo, Party Girls brings something new to the Northwest scene. Read more on Last.fm.
