German musicologist Konrad Ruhland (1932-2010) was an incredible scholar of Early Baroque and Renaissance music. This four disc set includes Gregorian chants performed by the Choralschola of the Niederaltaicher Scholaren and the capella antiqua Munchen, who Ruhland founded in 1956. This selection of recordings from RCA and Sony has been called “stimulating” and “unerringly robust” by Gramophone. The hypnotic beauty of these chants is timeless.
