The gig featured DJ sets from Radiohead’s Thom Yorke and 3D from Massive Attack, with members of Unkle, was held in an abandoned complex owned by Swiss banking giant UBS in east London.
With an invited audience of 100, the gig was a “thank you” from musicians to the movement, said its organisers.
The complex was taken over by the Occupy London movement three weeks ago and transformed into the Bank of Ideas; it is being used by up to 30 groups who have faced cuts to their services.
Organisers added that the concert was recorded and would be put on an album and soon be available on a “pay what you want” basis from the Occupation Records label.
Money would be distributed to the UK Occupy movement and to encampments around the world.
