To celebrate Bach's bicentenary of death in 1950, Grischkat compiled single movement cantata, with new texts, to a concert Vom Reiche Gottes (Of God's Kingdom),[2] following an idea by Albert Schweitzer.
[2] Grischkat recorded many Bach cantatas with the Schwäbischer Singkreis, beginning in 1951 with Jauchzet Gott in allen Landen, BWV 51, with soloist Margot Guilleaume and the Bach-Orchester Stuttgart.
[6] He led in 1953 an early recording of Monteverdi's Vespers of 1610, at least of several movements, with soloists including Margot Guilleaume, Friederike Sailer, Lotte Wolf-Matthäus, Heinz Marten, Werner Hohmann and Franz Kelch.
[7] He conducted Bach's Christmas Oratorio in 1972, with Maria Friesenhausen, Hildegard Laurich, Peter Wetzler, Bruce Abel, Schwäbischer Singkreis and Südwestdeutsches Kammerorchester Pforzheim.
[8] He performed and recorded Bach's Mass in B minor in 1958, with Friederike Sailer, Margarethe Bence, Fritz Wunderlich and Erich Wenk, Schwäbischer Singkreis and the orchestra of the 35th Deutsches Bachfest.
