It's all to promote the new RHCP album. You can see more on the main site here.
They're organising 6 listening parties (translation: you stand in a bar while the album plays) around the world today. The London one is in Hoxton Square. You'll also be able to listen online.
Follow all of the action using the hashtag #ImWithYou
