On October 20, Deutsche Grammophon will release "Boston Symphony Orchestra: Complete Recordings on Deutsche Grammophon," a limited-edition, 57-CD boxed set of the label's entire legacy of BSO recordings, reflecting the orchestra's spirit and character over a period spanning the years 1969 to 2017. Conductors include BSO music directors William Steinberg, Seiji Ozawa, and Andris Nelsons, as well as Claudio Abbado, Leonard Bernstein, Charles Dutoit, Eugen Jochum, Rafael Kubelik, André Previn, Michael Tilson Thomas, and John Williams. Instrumental soloists include, among others, Christoph Eschenbach, Gidon Kremer, Anne-Sophie Mutter, Itzhak Perlman, Mstislav Rostropovich, Gil Shaham, and Krystian Zimerman. Among the contents are six discs of recordings by the Boston Symphony Chamber Players; the first release of Shostakovich's Symphony No. 6 led by Andris Nelsons; and previously unreleased recordings under Seiji Ozawa of Brahms's Symphony No. 2 and the overture to Rossini's Semiramide. A lavishly illustrated booklet includes introductory essays by former recordings producer Thomas Mowrey and BSO Director of Program Publications Marc Mandel, and the individual CD sleeves reproduce the cover artwork of the original releases. "Boston Symphony Orchestra: Complete Recordings on Deutsche Grammophon" will be available for $199.95 in the Symphony Shop and at bso.org, and can be pre-ordered at bso.org.
