Bach The Orchestral Suite No. 2 by Bach is really a flute concerto, and this performance of it is very much as Bach would have heard it. Wilbert Hazelzet plays the low-tech Baroque flute. Ton Koopman leads the Amsterdam Baroque Orchestra, playing period instruments. They're in concert in the "New" Castle, an 18th century palace in Meersburg, Germany, next to Lake Constance.
