Rafael Lozano-Hemmer’s biometric portraiture

Rafael Lozano-Hemmer discusses Last Breath (2012), a mechanical sculpture that captures the breath of a given person in an imperfect attempt to retain their presence even after they have passed away. The iteration of this work included in SFMOMA’s Soundtracks exhibition displays the breath of the late experimental composer Pauline Oliveros, an influential Bay Area performer and teacher.
