This recording is a completion of an internationally acclaimed series: Aapo Häkkinen and the Helsinki Baroque Orchestra conclude the cycle of Bach's harpsichord concertos with the concertos for 3 and 4 harpsichords. Here, too, Häkkinen surprises in terms of instrumentation: The harpsichords represent different schools of instrument building (German, Flemish, French and Italian), resulting in a remarkably differentiated sound. With Miklós Spányi, Cristiano Holtz, and Anna-Maaria Oramo, Häkkinen is supported by experienced companions. This keyboard festival is rounded off with the monumental Duetto by the eccentric Bach pupil Johann Gottfried Müthel, presented by specialists Miklós Spányi and Aapo Häkkinen on two historic clavichords. The SuperAudioCD, recorded in Finland and Sweden, offers stereo and surroundsound.
