serge baghdassarians & boris baltschun are artists and musicians based in berlin and work together regularly since 1999. their work moves between aether, performance and installation. most recently they exhibited who cooks for you who cooks for you all at the fürstlich fürstenbergische sammlungen / donaueschinger musiktage, an installation in which language in the form of audio captchas reveals itself as a place where a correlation system (man / animal / machine) is staged. also recently, as a ccommission by documenta 14, they completed the trilogy common cents with a work entitled backing track. this performance turned radio piece reads a one-hundred year old sound recording as an unfinished piece, thus allowing for the production of additional "tracks", situating it between a mirror for princes from the 17th century and present-day financial instruments.
