"Night + Day" featured concerts, talks, film screenings and community events--collaborators in the festival included Florence Welch of Florence + the Machine, Robyn and Jehnny Beth of Savages, all of whom are included in the xx's new doc.

"Coming back to Brixton and just seeing how everyone just co-exists really beautifully, I love that," says the xx's Romy Croft. "'Night + Day' was originally just an idea to do something a bit different, and a bit more than just a gig. To be honest, we didn't know that these Brixton shows were going to become 'Night + Day'--it just sort of happened in an organic way because we were suddenly playing all these shows."
