'Endless Shout' asks how, why, and where performance and improvisation can take place inside a museum. The book documents a six-month series of experimental performances organized by the Institute of Contemporary Art, Philadelphia, where five participants Raâul de Nieves, Danielle Goldman, George Lewis, The Otolith Group, and taisha paggett collectively led a series of encounters and unfolding improvisation experiments. These include Miya Masaoka's 'A Line Becomes a Circle', which pays tribute to Shiki Masaoka, a subversive Japanese haiku writer; jumatatu m. poe and Jerome Donte Beacham's 'Let'im Move You', addressing the history of J-Sette, a dance form popularized by drill teams at historically black colleges; and 'A Recital for Terry Atkins' by composer George Lewis. The book further contextualizes the events through an essay by curator Anthony Elms, conversations with George Lewis, Jennie C. Jones, and Wadada Leo Smith on themes of rhythm, rehearsal, and improvisation, plus new works and writing from Raâul de Nieves, Cynthia Oliver, The Otolith Group, and taisha paggett.
