Vinyl LP pressing. Originally released on Klaus Schulze's Innovative Communication label in 1981, Sei still, wisse ICH BIN is Popol Vuh's 13th LP. Fricke and Fichelscher worked under the production of Klaus Schulze himself and were helped for the occasion by Chris Karrer on soprano sax, Renate Knaup on vocals and the Chorensemble der Bayerischen Staatsoper. Two of it's songs were used on the soundtrack of Werner Herzog's film Fitzcarraldo, from 1982.
