Recorded in 1980 and produced by Klaus Schulze, Sei Still, Wisse ICH BIN ("Be quiet, I am") is one of Popol Vuh's sacred music offerings. Like Hosianna Mantra nearly a decade before, this set is regal in its solemnity and in its intensity. Utilizing the Chorensemble der Bayerischen Staatsoper and the soprano saxophone stylings of Chris Karrer, Popol Vuh – down to a three-piece with vocalist Renate Knaup fronting the choir, Fricke on piano and voice, and guitarist Daniel Fichelscher holding down the drum chair as well, this is a huge recording.
