Imogen Heap's North American Tour Raises Money For Fan-Selected Charities

Imogen Heap has decided to "invigorate [her] musical eco-system" by playing a new improvised and fan-inspired song each night during her North American tour in support of the album "Ellipse," then selling the new track via her website.

Fifty percent of the money raised through each track goes to an individual charity selected by fans of that show. The other 50 percent goes into a big "win pot" which will go to the charity that receives the most votes at the end of the tour.

Over the years there's been many charities i've wanted to support but never have had the time to give them much. This way.. i get to spend 5 minutes on stage having great fun, the audience take part and experience the Heap creative cogs in motion and witness the performance of a piece of music that will only exist once. The local charity gets recognition, promotion and some cash from the downloads. Everyone's happy! For me, apart from a few logistics, set up time and costs... once it's up and running it's easy! In time there could be 100s of these pieces getting up to some good action.

The target amount of the fundraiser is $54,000. E-mail your suggestions to with ideas for nonprofits to promote.
