Had family outing to this at the o2 arena yesterday. Quite a good day out, especially the Gibson Interactive Suite. You can have a go on guitars, bass, drums, keyboards, vocals etc, and remix a track. Allows you to play/sing along with popular tracks and record your work and play it back on the web.
Although the only track you could remix was Queen's Radio Ga Ga, having said that it was quite a good way of showing someone around multitracking etc.
Exhibition itself wasn't too bad, they had a little bit about UK Reggae with interactive contributions from Dennis Bovell, Dave Hinds, LKJ and Lynval Golding from the Specials.
All in all something quite good to do on a sunday.
