The evolving musical climate of the 1950s occasioned a profound shift of culture and attitude in the performance of Bach’s great choral works. By the close of the decade, it was one of Bach’s own successors in the post of Kantor at Leipzig’s Thomaskirche, Karl Richter (who’d become organist there at age 23 in 1947), who’d become torch-bearer for a new generation of Bach interpreters. Richter’s recordings with the Munich Bach Choir and Orchestra (ensembles he founded in 1951 and with which his name has become synonymous) heeded an unbroken Leipzig tradition that could be traced back to the time of Bach himself.
Richter actually made a full set of recordings for Handel's Concerti Grossi. The Munich Bach Orchestra, who almost played exclusively for Richter, maintained its essential baroque flur throughout all the pieces, under the impeccable conducting of Richter. The different string sections played as if they were in a chorus, each minute part played in fully melodious and engaging manner, while the ensemble as a whole displayed all the required congeniality and harmoniousness essential of the baroque style. The rhythms are enlivened while contrasts striking, and you will seldom find Handel's works played in such grand style as did Richter and the Munich Bach Orchestra here.
Karl Richter's performance dates from 1965, since when it has seldom been out of the catalogue. It is in an entirely different class… Richter's Munich Bach Choir were at a peak at this time and the results are often quite exciting. Under Richter's direction the ''Ehre sei dir, Gott'' chorus…is appropriately lustig with wonderfully light-hearted singing and orchestral playing… [T]he arias with Gundula Janowitz and Fritz Wunderlich…[are] of a calibre which will always ensure considerable enjoyment…
As a Bach interpreter, Richter was almost unrivalled worldwide for many years and his Bach interpretations set standards. Karl Richter and his choir became the formative interpreters of the internationally renowned Bach Festival in Ansbach, a meeting place for the musical elite from all over the world. For almost two decades, the Munich Bach Choir and Orchestra has had the musical world from New York to Leningrad, from Tokyo to Paris at its feet, and many of its highly decorated recordings are among the best-selling recordings.
