P2Strom, the iPhone app + more
Håkan Lidbo and his associated at Swedish Radio electronic music program P2 Ström have created a new music-making iPhone app called "P2Strom" that lets friends jam together, choosing different instruments and so on. See/hear it in action: http://www.youtube.com/watch?v=EpwG4Zy6lf8
Even better, when you complete your track you can upload it to the Ström Soundcloud channel and if they like it, they will play it on the program.
In other Ström-related news, the latest theme of the current season is "Music from the Future" so they'll be playing a new track every week featuring one artist's interpretation of the subject which will then be compiled for a CD release at the season's conclusion.
