Arnold Schoenberg Chor is a renowned Austrian choir group known for its exceptional rendition of classical masterpieces. Formed in the 1970s, the group has undergone several transformations, with each iteration elevating the standards of vocal performances. Their repertoire encompasses a wide range of genres, including choir music, Austrian composers, and sacred pieces.

With a focus on choral music, the chorale performs various works of Austrian composers such as Arnold Schoenberg, Anton Bruckner, and Franz Schubert. Their rendition of Bruckner's Mass in E minor and Te Deum in C major is particularly noteworthy, showcasing their ability to balance intricate harmonies and emotional intensity. Additionally, their commitment to the music of Austrian composers is reflected in their performances of Theodora, A Village Romeo and Juliet, and Vespro della beata Vergine.

One of their most celebrated performances is the reissued edition of Theodora, featuring new cover art. The recording is notable for its evocative arrangement, which emphasizes the choir's vocal agility and control. Their rendition of Matthäus-Passion BWV 244 is equally impressive, with each vocalist bringing their distinct timbre and expression to the choral passages.
