This Sunday sees The Chemical Brothers take over Trafalgar Square for an evening of free music for the capital. Joined by Calvin Harris, the evening looks set to recreate the massive party Scissor Sisters had in the square last summer for the (Red) campaign.
The Chems will have a one-off lights-sounds-images show from United Visual Artists and Flat Nose George, which will make the evening all the more special.
So, we hear you cry, where can you get tickets from? Well, most went several months ago (completely passing us by), however the ICA (with whom the event is in partnership) have got a few left. All you need to do is answer the below question:
Which band did United Visual Artists collaborate with in 2003 to present stunning digital representations of realtime information about the world?
