Opening Performance Orchestra

Opening Performance Orchestra is a seven-member ensemble formed in Prague, Czech Republic, that first presented its work in public in 2006. The group draws on twentieth-century electronic avant-garde music and Japanese noise, and builds its pieces on what it calls fraction music, in which a source sound is digitally broken down until it loses its original character. Its working credo is no melodies, no rhythms, no harmonies. Opening Performance Orchestra also reworks music by composers it feels close to.
