September 15th 2026 will mark the 150th anniversary of the birth of one of the most influential conductors of the 20th century: Bruno Walter (1876-1962). This comprehensive box set brings together his complete HMV and Columbia Graphophone recordings. Spanning the 78-rpm era from 1924 to 1939, this collection also features the landmark 1949 magnetic tape recording of Mahler's Kindertotenlieder featuring Kathleen Ferrier, offering the first release of two previously unpublished takes. To ensure the highest fidelity, the finest available materials have been sourced, including pristine test pressings on vinyl from original metal work and near-mint superior commercial pressings. After undergoing high-definition digitization, the recordings were meticulously restored. This collection finally sheds a truer and more precise light on the artistry and genius of Bruno Walter.
