Greenbelt have today announced more additions to the music programme including jazz legend Courtney Pine, singer-songwriter Thea Gilmore, emerging folk sensation Blair Dunlop, “musical butterfly” Eska, agit-prop attitude from Grace Petrie, the final gig by funny acoustic hip-hoppers The Austin Francis Connection, and try your hand at soulful Sacred Harp Singing.

Their recent commitment to spoken word continues, with Inua Ellams bringing his National Theatre show The 14th Tale, Palestinian poet and activist Rafeef Ziadah, and World Slam Poetry champion Harry Baker. There’s performing arts for all the family, including How To Catch A Star by Blunderbus Theatre Company and Dreams of Philomina by Lunabug Theatre.

Returning speakers to the programme of ideas include Jim Wallis, Vicky Beeching, Rev Richard Coles, Maurice Glasman, Stella Duffy, James Cary and Symon Hill, and they’ll be joined by Anglican Alliance coordinator for Latin America Paulo Ueti.

There's also a full film programme, including selections from Tipping Point Film Fund and the Insight Film Festival; and there’s plenty to discover in their visual arts programme, including work by portrait artist Nicola Green and sculptor Sokari Douglas Camp. Plus firm festival favourites the Photo Flash Swap, The Art School and Life Drawing workshops.

Comedy will be provided by the irrepressible Milton Jones, the anarchic and amazing Barbara Nice, and – following his appearance on Anne Widdecombe’s documentary about comedy and Christianity – defender of the faith Paul Kerensa.

They have modern worship music royalty joining us in the person of Graham Kendrick, and see things from a different side with a celebration of wonder from The Sunday Assembly.

For young people and students, they have a return for the Big Top show for young people Shedloads, Cake and Debate, an introduction to activism led by The Christian Aid Collective, worship from Serum, sessions from the Student Christian Movement, big name artists in the Acoustic Cafe and a special programme of late night youth films.

Plus, an event to mark a UK response to the Kairos call from the Holy Land, and bring your dancing shoes for Greenbelt’s very special 40th birthday party…
