Composer and pianist Sam Post and pianist Ralitza Patcheva performed selections from their newly released album The Well-“Tampered” Clavier on Saturday evening, October 18, at the Episcopal Church of the Redeemer in Glen Echo. The concert celebrated the release of their reimagined version of Johann Sebastian Bach’s Well-Tempered Clavier, which keeps Bach’s original notes intact while transforming the music through fresh rhythmic interpretations. The recording, released Friday on the ACIS label, reimagines all 24 pairs of preludes and fugues from Bach’s first book.
