Put on those dancing shoes: Tate Liverpool is staging a musical courtesy of the US-born artist Christopher Kline, who plans to turn the gallery into a working set where visitors can drop in for a spot of singing, acting, lighting and set design (1 April-1 May). “O.K.—The Musical explores and restages the entire history and folklore of Kline’s hometown of Kinderhook in New York State with an original score by the artist,” a statement says. Members of the public will have the chance to see the production unfold in the gallery and can watch as local community groups rehearse, and make props and costumes. Curtain up!
