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, University of Pennsylvania, where five participants--Ra l de Nieves, Danielle Goldman, George Lewis, The Otolith Group and taisha paggett--collectively led a series of 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 at historically black colleges; and A Recital for Terry Admins by composer George Lewis. The book includes an essay by curator Anthony Elms, conversations with Jennie C. Jones and Wadada Leo Smith on themes of rhythm, rehearsal and improvisation, plus new works created specifically for the book, such as a script by The Otolith Group on blackness and digital color correction.
