The Russian-born conductor and composer, Igor Markevitch, was one of many composers fascinated by the various puzzles in the output of J.S. Bach. In The Musical Offering he calls for three orchestras – to clarify the work’s contrapuntal texture – and reorders the canons left incomplete by Bach, drawing them together into one continuous movement. The composition concludes with a six-part fugue whose style is at once grand yet dignified.
