Nikolaus Harnoncourt describes Mozart's Requiem as "an intensely personal confrontation, frightening and moving in the case of a composer who normally kept his life and experience divorced from his art to an astonishing degree". This famous recording uses an edition published by Eulenberg in 1972; seeking to come closer to the spirit of the composer himself, it replaces the familiar instrumentation of Franz Xaver S�ssmayr, who completed the Requiem after Mozart's death. For the 40th anniversary of this recording, Warner Classics has newly remastered it from original tapes in High Definition 192kHz/24-bit.
