website. What is most interesting about this project is that (as you can see by the poster on the side) the two film makers have enlisted the collaboration of a wide range of musicians. But as you look at the site they have also enlisted a lot of other friends of the project including companies like Deering Banjos.

This one seems to have been well organized and the director and editor did a lot of prep work - but the Kickstarter funding helped get them over the top. The two leads on the project also seem to have thought carefully about when a critical funding point was coming up. They were able to get 654 backers with about $70,000 in funding.
If you have not heard of Kickstarter check it out. Or better yet, see the results of this kind of swarming when the Porchlight Sessions video is released.
