Vesperae Solemnes De Confessore In C Major, K.339 / Ave Verum Corpus, K.618 / Missa Brevis ("Sparrow" Mass) In C Major, K.220

The Musical Heritage Society (MHS) released this compilation in 1966 to provide accessible, high-quality recordings of Wolfgang Amadeus Mozart’s sacred choral works to American households. By licensing European recordings, such as those featuring the Wiener Barockensemble and the Chorale Philippe Caillard, MHS played a significant role in democratizing access to classical repertoire that was often difficult to find outside of specialized music import shops during the mid-twentieth century.

The selection showcases Mozart's stylistic evolution, spanning from the early Missa Brevis in C Major, K. 220, composed during his tenure in Salzburg, to the mature Vesperae solennes de confessore, K. 339, and the late masterpiece Ave verum corpus. The production reflects the mid-century European approach to Baroque and early Classical performance practice, emphasizing clarity and liturgical reverence. These recordings were well-received for their balance of technical precision and the resonant, emotive vocal performances typical of Guschlbauer’s collaborations with the featured soloists and ensemble.
