Jack Conte and Nataly Dawn collaborate on music. This is what it sounds like.

-- From their Youtube channel

Where do you start with Pomplamoose?  They came to my attention via their cover of Beyonce's Single Ladies, which was a stroke of brilliance. Pomplamoose builds their music in layers, using video editing to create their music.  They call them Videosongs, and are clear to point out that if you hear it in the song, it's in their video.  This makes for very interesting videos, with tableauxs of several Nataly Dawns and Jack Contes on the screen.

Aside from their covers, however, they also create their own music, which is just as entertaining to listen to. In fact, they were one of my first iTunes purchase, breaking a long-standing opposition to paying for music online.
