NAXOS BACH, J.S. 2 CD - Bach's six unaccompanied Cello Suites, written around 1720 while he was in the service of the young prince Leopold of Anhalt-Cothen, are the first truly virtuosic works written for the instrument. Nearly three centuries after their composition, the Suites remain the supreme test of a cellist's technical & musical capability. Leading cello virtuoso Maria Kliegel performs them here on a cello made by Stradivarius in 1693.
