Watch Out Worcester takes place on the opening day of the Three Choirs Festival and as part of both events, at around 3pm, you can see Emily May Dance Theatre, Encompass Collective, and Dancefest's Chance to Dance Company in the riverside setting of Worcester Cathedral's west garden.
Four new are plays by young emerging writers, commissioned especially for the day, will be performed as part of Jumpstart from 2pm to 4pm, with a post-show discussion.
Worcestershire Resource Exchange (part of the Duckworth Worcestershire Trust) will be creating an installation piece entitled 'Portal' made from thousands paper feathers, all individually cut and made from reclaimed materials.
Worcester-born DJ Ed Steelefox will mix a musical response to the incredible space to create a thoughtful and reflective soundtrack to the coming-and-goings of the visitors and special guests.
Also at St Swithun's will be singer songwriter Shiraz Hempstock, and poet, writer and performer, Suz Winspear, who was Worcestershire Poet Laureate 2016-17. She'll bring a range of poets to perform during the afternoon, presenting poetry in new and unexpected ways, and maybe helping visitors to find the poet within themselves.
At around 4pm there'll be a mass movement performance by youth groups who've performed throughout the day.
Watch Out Worcester is produced by Dancefest in collaboration with Worcestershire partners including Jumpstart (part of Worcestershire Arts Partnership), The Hive, Three Choirs Festival, University of Worcester, Churches Conservation Trust, Severn Arts, Vamos Theatre, Worcester City Art Gallery and Museum, Worcester Arts Workshop, Worcestershire Litfest & Fringe.
