Marianthi Papalexandri’s work includes compositions for instruments and sound objects that she creates herself and in collaboration with artist Pe Lang, presented in a form of a live performance and audio-visual installation. Her work focuses on the reexamination and reinvention of the musical instrument as a sound generator, as well as the type of sound production and behaviour of the performer. Much of her work involves a continues interaction between the visual to the musical. It is also a work which demands absolute focus, clarity and economy of means.
