Collaboration Inspiration: Thru You

Via BoingBoing:

ThruYou is a seven-track dub and breakbeat album created entirely using samples from user-contributed YouTube videos. It's the coolest thing you'll see today, and not just because of the remix nature of it, but how it takes these amateur contributions and by contextualizing them draws out their best elements. Not so much the little clips cut into rhythm hits, but the solos.
