U2’s new single “Invisible” is now available to download via iTunes for free globally, and for every download, the Global Fund – via (RED) – will receive a $1 donation from Bank of America with the total donation dependent on how many people worldwide download the track.

“Invisible” will only be available for download through 11:59 pm EST Monday, January 3rd, where it then be removed from iTunes… at least for now.

In an interview with USA Today this week, frontman Bono confirmed that the track will be included on the band’s new album, but will not be the first single.

“We have another song we’re excited about to kick off the album,” he says. “This is just sort of a sneak preview — to remind people we exist. [Invisible is] the first one we finished.”

He also confirmed the band have not wrapped completion of the album but will continue to work on it “for a couple of months. We want it to come out this summer, but you don’t want to let anyone down.”

“Invisible” is produced by Danger Mouse and mixed by Tom Elmhirst. The video for the track is directed by Mark Romanek (Jay Z – 99 Problems; Johnny Cash – Hurt; Nine Inch Nails – Closer), 60 seconds of which will be shown during a Super Bowl ad break on February 2nd, and on YouTube from 8 pm GMT the same day.

(RED) was set up to channel funds to the Global Fund to fight Aids, TB and Malaria and has already generated more than $240 million* since being founded in 2006 by Bono and Bobby Shriver. 100% of the funds raised by (RED) go to the Global Fund as no overheads are removed.

(RED) funds are fighting AIDS in eight African countries — Rwanda, Lesotho, Swaziland, Zambia, Ghana, Kenya, Tanzania and South Africa – where they pay for AIDS treatment, testing and prevention services, with a focus on ending mother-to-child transmission of HIV and achieving an AIDS free generation. (RED) and its partners — from Bank of America, to Starbucks, Apple and more — are united in a global push to end mother-to-child transmission of the deadly HIV virus by 2015, in accordance with the UN Millennium Development Goals.
