The best X-Mal resource I've found so far is Poison Door... it's got a great photo collection, spanning their whole career, right from the days of the all-female line-up (Anja Huwe vox, Manuela Rickers guitar, Fiona Sangster keys, Rita Simon bass, Caro May drums) and their multicoloured hair. The biography is in German (which I can't speak, but I ran it through BabelFish); apparently, Anja Huwe emerged again briefly as a co-presenter of a music gameshow on NDR television.
