Stan Shields rehearses with a fellow actor Monday at Town Hall before performing in "365Days/365 Plays" with the Josh Beerman theatre group. The theatre group is part of a project by 52 Seattle artists and theatre groups performing playwright Suzan-Lori Parks' world premiere of the "365 Days/365 Plays" year-long cycle. While the plays themselves are very short, from three lines to three pages, taken as a collection, they explore the wide range of political and cultural themes found in Parks' full-length work.
