Concerto for three harpsichords in D minor, performed by the Netherlands Bach Society for All of Bach
From the YouTube notes:
In the Concerto for three harpsichords in D minor, performed by the Netherlands Bach Society for All of Bach, Bach plays with monophony and polyphony. It is a solo concerto, but then for three harpsichords. Sometimes all the instruments play the same melody, but then they go off on their own again. And even when they follow their own path, there are still always lines played by two, three or four hands together. When the harpsichordists are actually all playing something different, their instruments still sound like one big combined instrument.
Classic FM posted this amazing Vivaldi Concerto in which the musicians use plastic recorders and a Cassio keyboard. They achieve a remarkable sound.
