Alabama 3 will headline Glastonbury's Left Field stage in support of the Miscarriages For Justice Organisation (MOJO).
The band will take to the stage on Friday 27 June to raise support for the human rights organisation, which is dedicated to assisting innocent people both in prison and after their release.
It follows their recent gig at Brixton Prison, where Alabama 3 treated more than 100 inmates to some of their best known songs like 'Woke Up This Morning' in support of Rock Against Racism.
The Brixton band are also working with the Glastonbury Left Field team on a Rock Against Racism show at the Brixton Academy on Wednesday, 30 April, alongside Misty in Roots, the Levellers, Tom Robinson, The Thirst and Tony Benn, which will mark the 30th Anniversary of the famous Rock Against Racism Carnival.
Larry Love from Alabama 3 said: "We have always felt privileged to be associated with Paddy Hill and MOJO. Not only have they inspired our music but they've consistently proved that with integrity, passion and intelligence you can make a difference. Hopefully Alabama 3 can inspire people to dance and get everyone's MOJO working."
It is the first time that MOJO have had a presence at the Left Field, which supports various political and social causes related to injustice. The charity was set up by Paddy Hill of the Birmingham Six and John McManus, who are promising more acts and speakers on the Friday.
John McManus from MOJO said: "Since music is so often an intrinsic expression of freedom and hope, then there can be no better place to raise awareness about MOJO's work than at this years Glastonbury. We are delighted to have been invited to the Friday night slot at this years Left Field tent."
