Innumerable transcriptions of Bach’s music were made in the 19th and 20th centuries, and many of them bear the signatures of both well-known and lesser-known composers. Among the former are Bruno G. Seidhofler’s notable piano 4-hands version of The Art of Fugue (1937) and the splendid transcription of the Orgel-Büchlein by Bernhard Friedrich Richter (1902) that is featured on this recording. The artists’ approach here – in an advanced vein of historically informed performance – takes inspiration from well-established Bach performance practice and then filters that through two specific media: the chosen instrument of an early 20th-century upright piano and the set of performance indications scrupulously laid down by Richter, which range from tempo indications assigned to each chorale and numerous (yet not too intrusive) agogic signs, to the octave doubling he often added in the soprano and/or bass.
