Cleveland Public Theatre’s Big Box series consistently breaks new ground. Spawning new works of theater, dance, music and other media impossible to pigeonhole, this annual collection of world-premiere workshop performances is always an exciting, unique experience. Tonight’s double bill features Unintended Consequences and Into Pieces. The show starts at 7 and performances continue through Saturday at CPT’s James Levin Theatre. Tickets are $12 to $15.
