U2 Release 'Invisible' Video

U2 have unveiled the music video for "Invisible," a charity single released last month in conjunction with Bono's AIDS relief fund, RED. The vid, directed by Mark Romanek, sees the band playing before a massive screen to an adoring audience.

Following the song's premiere during the Super Bowl, it became freely available on iTunes for 24 hours with BOA donating one dollar for every download up to two million downloads.

Last week, Bono stopped by the BBC to dish on the progress of the band's upcoming album:

"We went back to why we wanted to be in a band in the first place. We were listening to the Ramones and Kraftwerk - you can hear both on 'Invisible'. It opened up a whole valve for me writing, it was like a damburst of sorts."
