The Kammersymphonie Berlin (Chamber Symphony of Berlin)
was founded by members of the Konzerthausorchester(formerly Berlin Sinfonie-Orchester), the Staatskapelle Berlin, and musicians from the orchestras of the Komische Oper and Deutsche Oper.  The inaugural concert took place in January of 1991, after which the ensemble quickly established its reputation among concertgoers in and outside of Berlin. In its founding years under the leadership of Artistic Director Jürgen Bruns, the ensemble performed, in addition to the classical repertoire, many first-rate but seldom-performed works between larger symphonic and smaller chamber music forms.  At the heart of its programs were works of the classical modern and ostracized music of the early 20th century. During these years, Berlin enjoyed a musical scene that was as fascinating as it was diverse.

In the past 20 years the Kammersymphonie Berlin has collaborated with important composers such as Alfred Schnittke and Jean Françaix and has given the first German performances of works by Schreker, Glasunov and Milhaud, among others.  World premiere performances of contemporary composers (Detlef Glanert, Victor Bruns, Anatol Vieru, Carlo Domeniconi) have been performed at concerts alongside more established classical and romantic repertoire, with a programmatic theme connecting these works to each other.

The interaction between different art forms is another unique aspect of the Kammersymphonie's programming. In addition to musical collaborations with theater (e.g. Peter Zadek), the orchestra has also accompanied dance productions(with Gregor Seyffert) and literature in concert (with Corinna Harfouch, Dieter Mann and Eberhard Esche).

The Kammersymphonie performs regularly in Berlin at the Konzerthaus and Philharmonie as well as other important locations throughout Germany.  Under their Artistic Director Jürgen Bruns they have accepted invitations to perform at the Ravello Festival (Italy, 2000), the Dresden Music Festival, the Kurt Weill Festival in Dessau (2001) and the International Festival of Music in Sion-Valais, Switzerland.  In October 2004 the Kammersymphonie played an important role in the creation of the Music Festival “Poland in Exile,” which took place in Berlin and highlighted the works of Polish composers living in exile, from Chopin to Tansman.

In 1998, the Kammersymphonie Berlin released its first CD to much critical acclaim, featuring the first-ever recording of Franz Schreker's Birthday of the Infanta and Ernst Toch's Dance Suite.  In 2002 the first recordings of Berthold Goldschmidt and Roberto Gerhard were released along with the second symphony of Kurt Weill.  In 2004 Sony Norway engaged the Kammersymphonie Berlin for a collaboration with the baritone Rein Alexander; this CD was honored with platinum in Norway.  In Autumn 2006, Deutsche Grammophon released a recording of works by Gerhard Frommel.  At the beginning of 2007, the label Capriccio released a CD with music set to two Andersen fairy tales by Andreas Pflüger, with Corinna Harfouch reciting the narrative.  In 2008 Deutsche Grammophon released a CD featuring Kurt Hessenberg's suite “The Storm” and the Concerto for Saxophone by Lars-Erik Larsson with the soloist Frank Lunte.

In 2001 the Kammersymphonie Berlin received a grant from the Ernst von Siemens Music Foundation and in 2002, together with Artistic Director Jürgen Bruns, the orchestra received a special grant from the Rheinsberg Music Academy and the State of Brandenburg.
