Sound Cloud is one of the slickest additions to the web in the last year, providing for musical artists a perfect venue for sharing and disseminating their sounds. Anyone can sign up for a free account where you can upload up to 5 tracks, which as far as I know can be of any size and length. Then you can embed these files with Sound Cloud’s amazing interface that allows people to comment at any given section of the song. Facebook, MySpace, and now WordPress are all super Sound Cloud friendly. If you ever wanna scan the Sound Cloud community, the Radio Clouds API is a good place to start.
Here’s Sam Brouse with “Under and Over” (First live band performance of this song was at Earth Night 2009).
