The composer Tristan Perich wrote Infinity Gradient (2021) for pipe organ and 100 loudspeakers, and this double LP of 500 copies from Erased Tapes was recorded with the organist James McVinnie at London’s Royal Festival Hall. Each speaker plays its own line of music from 1-bit electronics that Perich builds and programs himself. The circuits can only switch current on or off, and those pulses drive the speaker cones. The piece was first performed in Strasbourg in 2021.
