Straddling the fields of sculpture and performance, Naama Tsabar creates objects that function both as artworks and musical instruments. “Blood Makes Noise” included three sculptures that explored ideas of power, collaboration, and interpersonal exchange through the motif of doubling. In Untitled (Double Face) (2010/14) she conjoined two electric guitars so that they could only be played through a couple’s mutual efforts. A trio of performers generated sound with Work on Felt (Variation Three) (2014) by beating, stroking, or plucking the pair of taut piano strings attached to either end of a large felt panel. Closer (2014) was similarly bifurcated: a corner formed by two seemingly austere walls revealed a colorful interior space containing a microphone and guitar strings. In order to function musically, each of these works required personal negotiation and active, even intimate, physical engagement, adding a strong sense of psychological and emotional tension to Tsabar’s performances.
