The COB | Composers’ Orchestra Berlin

The COB is a large orchestra, with strings, horns and rhythm section, founded in autumn 2010 by composer & conductor Hazel Leach. The members of the orchestra are not only improvising instrumentalists, but are also the composers. There is no fixed line-up: the composers can select instruments from the pool, to develop a brand-new and innovative orchestral repertoire with stylistic influences ranging from classical to jazz and from folk to free…. the music written for this band has no exclusion zones.
Since its founding in the autumn of 2010 the COB has become an established part of the Berlin jazz-scene, with regular concerts in the Kunstfabrik Schlot and the production of 4 CDs and an audiobook.

The fifth CD , “Exoplanet”, with compositions by saxophonist Christian Korthals was released in April 2023. (JazzHausMusik 299).

The latest orchestral CD is ‘Holding Pattern’, released in 2022 (Jazzhausmusik 285).
