Bowerbird is pleased to present the Philadelphia premiere of Pierluigi Billone’s “1+1=1”, an 80 minute exploration into the boundless terrain of two bass clarinets performed by the California based duo of Samuel Dunscombe and Curt Miller. A student of Salvatore Sciarrino and Helmut Lachenmann, Billone’s music can sound elemental and primordial, yet at the same time achingly human. In “1+1=1”, a deliberate pacing and frequent pianissimo dynamic makes for an inward inquiry into the character of the bass clarinet while the doubling of the instrument allows for an pulsating resonance of microtonal shifts.
