U2, Jay-Z, Coldplay, John Legend and The Killers among the acts contributing to a groundbreaking digital music magazine launched on World AIDS Day. (RED)WIRE is designed to help eliminate AIDS in Africa - U2's performance of Greg Lake's 'I Believe in Father Christmas' is among the premiere tracks.

Sign up to (RED)WIRE here and check back here all week to learn more about the new service.

Watch U2 perform 'I Believe in Father Christmas'.

It works like this.

Every Wednesday, (RED)WIRE members receive an issue delivered to their desktop featuring exclusive music from some of the world's greatest artists. Half of the £4 monthly fee goes directly to the Global Fund to fight AIDS in Africa. Members who join before next Wednesday, December 10 will become "Founding Members" and receive the premier issue on December 10 as well as a special bonus song from Jay-Z.

When you purchase a memberships at www.redwire.com you can download a custom player that allows you to experience each issue in an 'immersive, visual, magazine-like interface'. For your £4 a month, your weekly digital music offering includes an exclusive song from a major artist, a song from an up-and-coming artist, a special piece of varied content (such as a digital short film or a reading from an artist or actor) and well as a window about the impact (RED) funds have in Africa.

The Global Fund will ensure that every cent from (RED) WIRE is invested in HIV and AIDS programmes in Africa: five members will generate enough money, each month, to buy antiretroviral medicine for one person living with HIV.

At the same time (RED)WIRE creates a new revenue stream for artists and labels and an innovative way for consumers to discover new music. (All (RED)WIRE content is DRM-free and can be burned to a CD and played on any device.)

Don MacKinnon, president of (RED)WIRE, conceived the service to help create a platform for music discovery and an annuity to buy medicine for Africans living with HIV: "Every week, when you receive this great music, you'll know you are helping people in Africa get the medicine they need. It's that simple."

"Don MacKinnon just might be the penicillin the ailing music business needs." added Bono, co-founder of (RED). "He is an innovator by nature and I have no doubt that some of the music software we are working on at (RED) will help change the way music is received and change the lives of Africans who will die without the AIDS drugs that (RED) can help provide."

Content from (RED)WIRE will also be regularly posted on iLike for streaming and sampling to the site's 30 million registered users.
