U2 debuted a brand new song during the Super Bowl on Sunday, and they're giving it to fans for free for 24 hours.
"Invisible" became available as a free iTunes download at 6:00 p.m. Sunday and will be available through 11:59 p.m. Tuesday, and then it will be taken down from the iTunes store.
Bank of America will donate $1 for each download, up to $2 million, to (RED) — the non-profit organization to support the Global Fund to Fight AIDS, Tuberculosis and Malaria co-founded by Bono and Bobby Shriver.
Check out a Vine video the band posted to promote "Invisible":
Check out the teaser for the song the band posted on YouTube Thursday:
"Invisible" is not the first single from U2's upcoming new album.
Bono tells USA Today, "We have another song we're excited about to kick off the album. This is just sort of a sneak preview -- to remind people we exist." He adds that the band will continue to work on the album "for a couple of months. We want it to come out this summer, but you don't want to let anyone down."
