This is something the amazing Green Day Authority used to do many years back, inspired by Rivers Cuomo of Weezer. Here's the only proof I can find of that - http://www.greendayauthority.com/news/201/ It was called "Record A Sawng", and it kinda went this way - 1. They selected a Green Day song (sawng?), probably out of popular vote. 2. Week-by-week, the song was constructed. Every week, one instrument was dealt with. For example, Drums in week 1, bass in week 2, rhythm guitar in week 3 and so on.. 3. Fans sent in their entries each week, playing the required instrument exactly as it was played in the original, but originality/uniqueness was not at all discouraged. Usually, the drum track recording was to be done in sync with the original song (to avoid confusion), and the subsequent instruments/vocals were done over the drum track. 4. In the weekend, the forum voted for the best individual recording, and next week the process repeated for another instrument. Since Green Day uses a maximum of 4 instruments in most of its songs, the whole process took about a month. 5. In the end, all the instruments were mashed together and mastered by some guy. This gave them a beautiful final mix, made lovingly by contribution of the fans. I used to take part in those projects, and I think I may be wrong but I remember Mike Dirnt (bassist of GD) even acknowledging and praising it. I know, our community has an amazing monthly mix-up contest, but its basically based on individual talents. How about doing something similar to this, and get the whole community involved at the same time? I know its a really huge project to take on, but we guys are the largest LP fan site, maybe we can do this.
