Invisible

"Invisible" is a song by Irish rock band U2. Produced by Danger Mouse, it was released as a non-album single on 2 February 2014. The song was unveiled in a Super Bowl XLVIII television advertisement, launching a promotion that offered the song as a free digital download in the iTunes Store from 2–3 February. For each download of the track, Bank of America donated $1 to (RED), an organisation co-founded by lead vocalist Bono, to fight HIV/AIDS. Ultimately, $3.1 million was raised during the 36-hour promotion. Since 4 February, "Invisible" has been available as a paid download that continues to benefit (RED). Written and recorded during the sessions for the band's 14th album Songs of Innocence, "Invisible" was the second non-album single to be issued leading up to the album's September 2014 release, following "Ordinary Love" in 2013. A longer version of "Invisible" was later included as a hidden track on certain deluxe editions of Songs of Innocence. Lyrically, "Invisible" was inspired by the group's early experiences of leaving home to play in London with the desire to be noticed by audiences, as well as Bono's tumultuous relationship with his father. The song, described as an electronic-tinged rock anthem, was met with generally favourable reviews from music critics. The song has also charted in several countries, and topped the Billboard Adult Alternative Songs chart in the United States. A music video for the song was directed by Mark Romanek and released on 11 February 2014. U2 performed the song on the premiere episode of The Tonight Show Starring Jimmy Fallon on the observation deck of 30 Rockefeller Plaza in New York City. Writing and composition "Invisible" is an electro-tinged rock anthem. It begins with a "brittle, electronic passage," reminiscent of Joy Division. Simple keyboard movements and chiming guitars lead to a "sky-scraping chorus," and lyrics "harnessing notions of self-respect, both the personal kind and the universal-struggle kind." The song was written during the recording sessions for their 13th studio album Songs of Innocence, for which they began working with producer Danger Mouse in 2011. Lead vocalist Bono said that during the process of writing new material, they "went back to why we wanted to be in a band in the first place. It opened up a whole valve for me writing and it was a dam burst of sorts. Punk rock and electronic [music] was when it started for us.
