I love the DIY, make-shit-happen, mass collaboration aspects of the REMIXIN Project:
The key idea of remixin is to evolve music by creating a never ending web of remixes. Someone remixes one track, another person remixes that remix, then another person remixes that remix and so on. What you end up with is an ongoing chain of related works. Remixes can be in any style or tradition you wish. All styles of remixes are encouraged.
