Claudius von Wrochem (born 24 April 1965) is a German cellist.

## Life

Born in Berlin, Wrochem studied cello with Peter Mann in Berlin from 1978 to 1984 and with George Neikrug [de] in Boston from 1987 to 1990. He attended masterclasses with George Neikrug, Uzi Wiesel [de] and Werner Thomas. From 2000 to 2009, he took singing lessons with Juliane Gabriel in Berlin.
He is particularly interested in chamber music and contemporary music. He played in the "Duo von Wrochem" with his father, the pianist Johann Gottlob von Wrochem [de], from 1983 to 2006. He devoted himself to Neue Musik as a member of the ensembles work in progress - Berlin (1991-1998) and UnitedBerlin (1995-1998). Together with his wife, the musicologist and violist Simone Heilgendorff, he founded the Kairos Quartet in 1996, specialising in music after 1950.) Since 1993, he has been engaged in the performance practice of baroque and classical music, mostly in changing instrumentations; he uses a cello by J. G. Thumhart, 1780, for this purpose.
As improviser he works both freely and in terms of concept improvisations, often in the context of silent films, readings, exhibitions or in educational contexts.
In the function of artistic director, he led the start-up phase of the IZZM (International Centre of Contemporary Music) in Carinthia/Austria in 2009/10.

In addition to the standard repertoire for cello and piano and some recent duo works such as Morton Feldman's Untitled Composition/Patterns in a Chromatic Field, Wrochem played the Bach Suites I-V, a Reger suite and solo works by Bloch, Hindemith, Ligeti and many other contemporary composers. His extensive repertoire of string quartets can be found on the homepage of the Kairos Quartet.
