Ond of which is now available. Belgian harpsichordist Mario Sarrechia plays the solo part in the two concertos BWV 105Johann Sebastian Bach wrote six harpsichord concertos and compiled them in a volume around 1738. Most of his concertos for one or more harpsichords are probably arrangements of earlier concertos, mostly by Bach himself. The 'grand seigneur of early music' Sigiswald Kuijken combines Bach's six harpsichord concertos and the three double concertos for two harpsichords with the two violin concertos and the double concerto for two violins, which Bach also arranged as harpsichord concertos. All twelve concertos appear in a series of three CDs, the sec2 & 1058, Taiwanese harpsichordist Hsiu-Tzu Ryanas in the concerto BWV 1056, and Sigiswald Kuijken himself takes the solo in the violin concerto BWV 1042. Sigiswald Kuijken casts all the orchestral parts as soloists, as is customary with La Petite Bande and as was probably also practised by Bach - a theory that Kuijken underpins with ample evidence.
