The choir performs at festivals (e.g. "International Jazz Vocal Festival Russia", "Montreux Jazz Festival", "Rheingau-Musik-Festival"), in concert halls (incl. "Sunflower Hall", Yokohama; "Cappella", St. Petersburg; "Palais de la Musique", Strasbourg, Vienna Konzerthaus, Großes Festspielhaus Salzburg), in churches (Convent church, Zlatá Koruna; "Christianskirken", Århus; Magdeburg Cathedral), as well as in Jazz clubs ("Sweet Basil Club", Tokyo; "Jazz Art Club", Moscow; "Stadtgarten", Cologne).

The Jazzchor’s programme encompasses vocal jazz from swing to fusion, striving to bridge the gap between popular and art music, virtuosity and entertainment. The various arrangements of songs by important Jazz artists such as Miles Davis, John Coltrane or Nat King Cole are mostly composed by Bertrand Gröger and become very colourful with the addition of scat sections, collective rap and shout choruses. Through occasional excursions around the world by "Manhattan Transfer" or the "New York Voices", the choir brings well-known songs in quartet arrangement to the public.

In addition to numerous a cappella pieces, the choir is accompanied in concerts by its band that consists of piano, double bass and drums. The group is often expanded to include guest soloists on saxophone, tap dancers or solo singers. Previous collaborations have included the Swingle Singers, Bernd Schlott, Torun Eriksen, Cécile Verny, Norbert Gottschalk and Tap for Two.

On top of their vocal jazz programme, previous projects have included performances with Bobby McFerrin ("Circlesongs", "VOCabuLarieS"), the Bamberg Symphony Orchestra ("der und die (das)" by Bertrand Gröger), the Freiburg Philharmonic Orchestra ("Daphnis & Chloë" by Maurice Ravel), the Basel Sinfonietta ("Porgy & Bess" by George Gershwin) and the Hannover Big Band ("Concert of Sacred Music" by Duke Ellington).
