I've been visiting the Ninja Tune Forum for about a decade now. Aside from being populated with some great people, it's populated with greatly talented people who share a love of music.
There have been many excellent outcomes from hanging out there, from remixing other people's tunes to being introduced to new artists through to these increasingly creative collaborative projects. I've been part of relay mixes and different types of challenges but I think the Cut & Run project I did this week is one of the most innovative.
Update: hear the result here!
