This recording, led by the Furtwängler-like Barenboim and gloriously played by the Chicago Symphony Orchestra, replaces the scrappy Marco Polo release and certainly sonically outclasses the composer's own performance on Orfeo, but the leisurely tempi employed by Barenboim (seven minutes slower than on Marco Polo and two minutes slower than the composer's) mean that it requires two CDs rather than one. Not a masterpiece, but a masterly performance of a work that deserves to be heard more often. -Robert Levine Binding Audio CD.
