On the album for a•pe•ri•od•ic

  • Avant Music News, review: ‘The group . . . performs works biased toward various kinds of indeterminacy, whether of orchestration, sound material, or architecture. Silence also plays a major role in their music, whether as primary material or as a structural element.’

  • Chicago Reader, concert preview: “The record’s four pieces, composed respectively by Billie Howard, Michael Pisaro, and ensemble members Kenn Kumpf and Nomi Epstein, showcase a•pe•ri•od•ic’s rigorous execution of scores whose parameters include indeterminacy.”

  • Included in the Chicago Reader’s “Our favorite music of 2014”

  • Review by Brian Olewnick: “Like all the works on this release, and common to Frey, the performers have wide latitude with regard to their negotiating a way through the score, here choosing when to initiate and play their two lines. Akin to the above, though sounding quite different, there's a strong feeling of shifting masses, here more laminar and semi-solid. So lovely when, as near the conclusion, the bulk of the instruments subside, leaving a lone voice, in this case piano. Beautiful piece.”
