marta sainz is an improviser who uses her voice and body to conduct her investigations of sound. her work draws from butoh, german expressionism as well as artaud’s theater of cruelty. she seeks to create an emotional shock for the spectator as they experience all aspects of her total performance. she also performs with lali barrière in the duo, un coup de dès; with miguel a garcía and enrique zaccagnin in the group destruction des animaux nuisibles; and in a duo with maryah marymoto.

her first album for pan y rosas consists of three pieces of free improvisation, recorded at home, in one take, in november of 2012 and january of 2013. she used her voice, objects, a ukelele, an analog synthesizer and various effects to create this, el sonido de las entrañas.
