Aperiodic * Aus Der Nacht [New CD]

a·pe·ri·od·ic is a Chicago-based experimental music ensemble founded in 2010 and directed by Nomi Epstein, featuring post-Cagean notated experimental music. Their second release on New Focus features an album-length work by Magnus Granburg written for the ensemble, Aus der Nacht, von den Wehen, a forty-five-minute episodic work comprised of 71 distinct sections that explore subtle changes in attack, decay, resonance, and pitch, using an indeterminate notation to inject variability into it's performance.
