Babel is the second studio album by British folk rock band Mumford & Sons. As with Sigh No More, the album was produced by Markus Dravs. The vinyl LP version of the record was pressed by United Record Pressing in Nashville, Tennessee. It was released on 21 September 2012 in Ireland, Germany, Belgium, the Netherlands, Luxembourg, Norway, Australia and New Zealand. It was released on 24 September 2012 in the United Kingdom, Scandinavia, Spain, Italy, Eastern Europe, South America, and on 25 September 2012 in the United States and Canada.

Upon its release, Babel debuted at number one on both the UK Albums Chart and the US Billboard 200. It became the fastest-selling album of 2012 in the UK, selling over 159,000 copies in its first week, and was the biggest selling debut of any album in 2012 in the US at the time, selling 600,000 in its first week. The album received generally positive reviews from music critics and was nominated in the category of Album of the Year for both a Brit Award and a Grammy Award, winning the latter.

n late 2010, Mumford & Sons had already begun road-testing new material that they had been working on. Most of these songs, including "Broken Crown" and "Below My Feet", had already been played live on numerous occasions before the album's release. "Not With Haste" was a re-written version of the song "Learn Me Right" which they had performed with Birdy for the soundtrack of the film Brave. Mumford & Sons decided not to change their sound on Babel, which is the follow-up to 2009's highly successful Sigh No More, which elevated them to international fame. They did, however, admit that they purposely took their time in order to perfect the sound that they had already developed.

After a year of speculation , it was finally announced via their official website on Monday, 16 July 2012 that their new album Babel would be released in the UK on 24 September, and the following day in the US. A final track list and album art were also revealed, as well as a 30-second promo. Babel was made available for preorder on the band's official website on Monday, 23 July, when it was announced that the album would also be released as a vinyl LP and a deluxe edition with additional tracks.
