The Vienna ORF Radio Symphony Orchestra is presenting two exceptional experimental projects, with premières of the composer, performer and radio artist Elisabeth Schimana and music producer, remixer and DJ Patrick Pulsinger. In her “Virus” series, Elisabeth Schimana pursues what at first appears to be a paradoxical concept: the score to which the musicians play is not visible but audible. A flurry of the productive inaccuracy of playing together puts the audience in an acoustic house of mirrors. Pulsinger too places the orchestra in a relationship with an external other. The orchestra and the electronics transform the “voicings” created by a Rhodes piano into an after-hearing and play-along exploration of acoustic possibilities, deriving the power of musical narrative from difference.
