The German group Blutengel (Blood Angel) were founded by singer Chris Pohl, after contractual and legal problems forced him to exit the popular German band Seelenkrank. An electronica pop group with goth overtones, the band has gone through a few member changes while sticking to a configuration of one male and two female singers. They sing in German and in English, with lyrics exploring love, passion, and romance in highly dramatic tones. The original two female singers were photographer and singer Nina Bendigkeit (another Seelenkrank alumni) and Katie Roloff. Bendigkeit left after the debut album, Child of Glass, was released to modest club success in 1999, to devote time to her growing success as a photographer. It was an amicable parting, as Bendigkeit would later work on the band's publicity materials; she was replaced as a vocalist by Gini Martin. The next album, Seelenschmerz, continued to develop the band's fan base in Germany, with several singles garnering airplay; it was enough for Pohl and the group to finally perform live, and their debut performance was for 10,000 fans at a festival in Leipzig. The success strained relationships in the band, and in 2001 both Roloff and Martin left Blutengel to found the group Tristesse de la Lune, stating that Pohl's leadership had become overbearing. They were replaced by Eva P÷lzing and session singer Constance Rudert.
