Daniel Barenboim was named music director designate of the CSO in January 1989, and he assumed leadership as the Orchestra's ninth music director in September 1991, a position he held until June 2006. His music directorship was distinguished by the opening of Chicago's new Symphony Center in 1997, highly praised operatic productions at Orchestra Hall, numerous virtuoso appearances with the Orchestra in the dual role of pianist and conductor, twenty-one international tours (including the first to South America) and an ongoing series of composer perspectives woven into the Orchestra's subscription concerts as well as numerous recordings. + It is Barenboim's acclaimed recorded legacy with the Chicago Symphony Orchestra that is celebrated with the release of these three incredible boxed sets.
