For the Cincinnati Symphony Orchestra, Chris Kallmyer presents a new film in Springer Auditorium at Cincinnati Music Hall that contains within it all music that could ever happen ever. Kallmyer takes an expansive definition of music, including formal performances, imagined sonic situations, and reconfigured concerts described in handwritten scores that move across the screen and depict a world that is made largely of speculative music — a blissful symphony for an audience of careful listeners, bangin’ dance music in a cabin set deep in the woods, a solo contrabass alone on a mountaintop, or avant-garde drum machines that heal the earth and its people.
