Rotapoems, dedicated to Dieter Roth, are in fact 6 versions of a poem in Roth's lyrical collection "Scheisse," Providence 1966. They are a return to a form Williams first used in his book "Konkretionen," Krefeld 1959, and the "Litanies for Alison Knowles," placed in a musical landscape by Dick Higgins in 1966. The vowels of Roth's original poem are shifted progressively from version to version, resulting in constant sound changes and frequent alterations in sense. They are meant to be read aloud." -- Source of annotation: Marvin or Ruth Sackner.
