Radiance was commissioned by Duo Montagnard, and written for Joseph Murphy (saxophone) and Matthew Slotkin (guitar). The piece is part of a series of works that use the audience’s smartphones as a sound system. Music played on stage is selectively sent to a broadcast, which is followed by the audience on their devices. The sounds that appear are delayed, and everybody’s delay is different, so what you get is a kind of spatialized digital delay, with audience participation.
The piece itself unfolds in large sectional loops that can be mostly tracked through a signature motto played by the guitar at the end of most sections. Meanwhile, the piece is both driving and soaring (note to self: “Make clouds of arpeggiated chords that can float through cell phones”), seeking to engage saxophone and guitar in a wide variety of textural combinations, harmonies with chord extensions, and instrumental colors. The audience’s contribution provides the “radiance” for the players.
As a composer, I am super thankful to Matt and Joe for their hard work and dedication in helping to develop this piece, in performing it so well and so often, and for producing this beautiful and detailed recording.
