I don't know about you, but the most interesting thing I've seen in music this year hasn't been Friendly Fires, Empire of the Sun or even the new Sugababes line-up. It's been reactive music.
Reactive music is a whole new genre of sound that uses sensory input to generate and control the music you're listening to. If you've got an iPhone you can start having a play with it now. Just download the RjDj app and it'll start sampling noise from the world around you and looping it into a kind of weird, trippy music track. It's mind altering stuff, but VERY cool - and a completely new way of participating with the music you're listening to, not to mention the world around you.
For those of you without an iPhone, just watch this and pretend it's your house...
Like all new tech, it'll take a while for reactive music to find its place in the world. But in a world that loves relevance, personalisation, interactivity and entertainment, and where technology is moving ever faster, the creative potential of a feedback loop from you and your environment to the music you're listening to, the pictures you have on your walls, the clothes you're wearing, your Facebook page or whatever seems massive.
Definitely one to keep an ear out for in the future.
