Since 1987 Christian Kesten interprets New Vocal Music and New Musictheatre, as soloist or as a member of the ensemble "Die Maulwerker" ["Mouth/Muzzle Workers / Loudmouths"].
He has performed in Tokyo, Moscow, Israel, Czec Republic, Slowakia, Austria, Switzerland, Germany, Italy, Spain, France, Belgium, Luxemburg, the Netherlands, Glasgow, New York, Rio de Janeiro.

Breath music, country, falsetto, larynx sounds, Lied, opera, overtone singing, pop, song, tongue sounds, yodeling, the sounds of maybe nine different languages, plus miscellaneous gibberish: he is known as a specialist for vocal experiments; for steps between borders, in the soundscapes between music and language, music and theatre, for experiments with music in space, with sounds listening to silence.

Kesten developed a repertoire of extended vocal techniques, which focus on noise and subtle nuances of sound colours. His vocal practice is rather abstract an "non-psychological". The sounds have space to be perceived in their specifics.
He was influenced through the work with open, conceptual scores of the experimental tradition, which want the interpreter to be a co-composer. The awareness for silence and the interpenetration of sounds lead to a physical presence of his performing and the sense of space.

In a long collaboration with Dieter Schnebel, he did most of the first performances of Schnebel's musictheatrical works. He is known as an important Cage- and Fluxus-performer (collaborations with Emmett Williams (1999-2007) and Alison Knowles (2008)).
