German musician born 1962 in Bingen/Rhein. Brother of Bernhard Klumb.
As Jay Kay, he was part of early New Wave band Aus 98, Post Punk and Hardcore band Circle of Sig-Tiu and Dark Wave band Forthcoming Fire. In the mid 1990's, he mainly used this alias for his works. In this period, Klumb tended more and more towards right-wing and pagan positions. Besides works of Forthcoming Fire, his band projects Weissglut, Von Thronstahl and Unternehmen Dreizack underline these positions.
