RjDj, the music application for iPhone and iPod Touch users, has released its second album, Shake. While RjDjs recently-released debut album used external noises and voices in proximity to dynamically create music while it is being played, the Shake album incorporates external movement. Listeners can now play with music and create their own tracks by tilting, twisting, waving and shaking their iPhone or iPod Touch.
The album uses the iPhones accelerometer to adjust the audio any time the phone senses movement.

The Shake album includes Roman Haefelis Amenshake scene, a dance scene that reacts to movement by producing drum and bass sounds, as well as a scene from Amaury Hazan which requires sometimes wild movements to create specific musical sounds. Anyone you see who appears to be trying to smash or shake their iPhone to death is most likely listening to Amaurys Strike scene, RjDj says. Other scenes react to movement by producing acoustic feedback, controlling a variety of different musical instruments or scratching music in ways that would be difficult to recreate on a turntable.

The mind boggles at how technology can now be used to create compelling new music experiences, says RjDj Founder Michael Breidenbruecker. This new album required an enormous amount of work, but has been immensely enjoyable to put together. We cant wait to see how it is received.

RjDj was developed by the team behind Last.fm and has enjoyed hundreds of thousands of downloads since launching in October 2008.
