Other Minds is pleased to present Polytempo Music, a new recording by American composer Brian Baumbusch with the San Francisco Contemporary Music Players. Polytempo Music draws influence from Indonesian gamelan music and minimalism, with their interlocking rhythms, stable harmonies, and kaleidoscopic instrumental colors. Conceptually, it also owes a debt to Conlon Nancarrow's rhythmic experiments. Building on those foundations, Baumbusch invites us to explore an advanced heterophony—multiple instruments playing variations of the same melody simultaneously. Polytempo Music will be issued in three different formats simultaneously: as a compact disc on Other Minds Records; as a virtual reality application for the Meta Quest headset; and as a mobile app for both Apple and Android users. The two apps will be issued on Baumbusch’s Holography label.
