Forty-five years young, British hard rock royalty GIRLSCHOOL unveils their hair-raising new single "Cold Dark Heart", taken from their fourteenth studio album "WTFortyfive?", set for release on July 28 via Silver Lining Music.

Musically, "Cold Dark Heart" unveils a more somber and dark side to GIRLSCHOOL. The tracks kicks off with a chugging, boot-stomping guitar riff, entangled with hypnotic vocals, eerie lyrics, and accompanied by a mesmerizing video with scenes of an otherworldly fantasia, created by Instagood Promotion.
