Like many of Bach's sets, such as the Goldberg Variations or the Well-Tempered Clavier, the Brandenburg Concertos form a kind of master anthology - a demonstration of all the imaginable possibilities inherent in a certain musical form. Each of these six concertos calls for a different combination of soloists, every one unprecedented in it's choice of instruments. This recording from the superb English ensemble Florilegium goes in reverse of the numbered order, so that each piece adds to the musician complement.
