A (Soma)tic collaboration, ARTHUR ECHO documents a Winter 2009 day Conrad and Donovan spent listening to cellist Arthur Russell's WORLD OF ECHO on a twelve-hour loop in a five-story Philadelphia house. This chapbook appropriately inhabits the pop music tradition of the split single, as both poets tune into Russell's masterpiece to generate separate sets of notes on occult topics like angel milk & rock salt, the nutritive body, ecophenomenology, and lyric poetry. A unique tribute to Russell that conjures a reverberant portrait of close-listening and vital friendship from perceptual flux.
