8pm: Emmanual Jal, one of Africa's hottest hip-hop stars, who was a child soldier in Sudan until a British aid worker rescued him, turns up in the London studio to record "Gua". Jal said: "I found it important to take part because of what they are doing for children in a war-torn place. I know how terrified they are. I'm asking people to pick up responsibility before another child picks up a gun." In Oxford, Radiohead produce"I Want None Of It" and in Liverpool, The Zutons record "Hello Conscience".
9pm: In Newcastle, Mercury Prize nominees Maximo Park are making the single "Wasteland".
10pm: Back in London, the technical team are working flat out as the tracks start to flood in. Time is running out to ensure the album is ready for download.
