Qntal is a German "electro-medieval" band founded in 1991 by Michael Popp and Ernst Horn. They later added vocalist Syrah (Sigrid Hausen) to complete the band. It has roots in Estampie, a band of similar genre but different style; Michael Popp and Syrah are the principal members. Horn left the group in 1999, to concentrate on his other band, Deine Lakaien. He later formed Helium Vola in 2001. Philipp Groth (a.k.a. Fil) then joined Qntal. In 2008, singer and violist Sarah M. Newman (Mariko) left the New York based band Unto Ashes to work with Qntal and Estampie in Germany.
