Bach arranged various Vivaldi concertos for organ and harpsichord. The Concerto in A minor, performed by Siebe Henstra, Menno van Delft, Pieter-Jan Belder and Tineke Steenbrink for All of Bach, is largely based on Vivaldi's Concerto in B minor for four violins and orchestra. But of course, he gave it an exciting twist, as in Bach’s version the soloists play harpsichords and B minor changed to A minor.
