Invisible was a song later included as a hidden track on which thirteenth U2 album?
Invisible (U2 song) "Invisible" is a song by Irish rock band U2. Unveiled in a Super Bowl XLVIII television advertisement, it was available as a free digital download through the iTunes Store from 2–3 February 2014. Bank of America gave $1 for each download of the track to (RED), an organisation co-founded by Bono, to fight AIDS. Since 4 February, it has been available as a paid download, with all the proceeds also going to (RED). The song was later included as a hidden track on the deluxe edition of the group's 2014 studio album "Songs of Innocence".
Elevation Tour The Elevation Tour was a worldwide concert tour by the Irish rock band U2. Launched in support of the group's 2000 album "All That You Can't Leave Behind", the tour visited arenas in 2001. After the band's previous two extravagant stadium tours, Zoo TV and PopMart, the Elevation Tour returned the band to indoor arenas with a much more stripped-down, intimate stage design. A heart-shaped B-stage extended from the main stage, while encapsulating many of the fans.
