Tölzer Knabenchor, Collegium Aureum Dir. Gerhard Schmidt-Gaden, Hans Buchhierl, Mario Krämer, Werner Krenn, Barry McDaniel ‎– Mozart Requiem KV 626

Released in 1977 by Deutsche Harmonia Mundi, this recording of Mozart's Requiem represents a significant effort to present the work through a historically informed lens. The collaboration between the Tölzer Knabenchor and the Collegium Aureum aimed to move away from the heavy, romanticized interpretations prevalent in the mid-20th century. By utilizing period instruments and a boys' choir, the ensemble sought to recapture the lean, transparent textures intended by the composer, reflecting the growing influence of the early music movement in Western classical performance.

The production features the Tölzer Knabenchor, a German boys' choir renowned for its technical precision and crystalline vocal quality under the leadership of Gerhard Schmidt-Gaden. The use of boy sopranos and altos to perform the solo lines, alongside established vocalists like Werner Krenn and Barry McDaniel, highlights the intentional contrast between youthful timbres and professional operatic experience. The recording was well-received by scholars and critics at the time for its scholarly approach, which favored clarity and structural balance over the dramatic excesses often applied to Mozart's final, unfinished masterpiece.
