On April 24, Matthews debuted soon-to-be lead single "Mercy" on
Late Night with Jimmy Fallon. In May, "Gaucho" was made available for download from the band's website for members of the Warehouse Fan Association, although the song did not receive an official single release. Numerous tracks that would be included on the album—"Mercy", "Gaucho", "Sweet", "If Only", "The Riff", "Rooftop", "Snow Outside", and "Belly Belly Nice"—were all played on the band's 2012 summer tour. During the week leading up to the album's release, it was available to stream for free on
iTunes. The album's title was taken from a lyric in "The Riff": "Sitting in a box/away from the world out there", which, according to Matthews, relates to the idea that "we are born and die alone" and that "our body is our box".
Commercial performance The album debuted at No. 1 on
Billboard 200 with album sales of 266,000 in its first week, becoming the band's sixth consecutive album to top the chart. By the end of December 2012, the album had sold 458,000 copies. The album also peaked at the top of
Billboard's Top Rock Albums chart, and reached No. 3 in Canada. The second single, "If Only", was also successful on the AAA chart, reaching number 11. Ritt considered primarily acoustic tracks such as "Sweet" and "Belly Full" to be among the album's highlights, saying that their stripped-back arrangements "unearth a simple truth: these are genuine craftsmen."
Classic Rock praised "Mercy"'s "tender
John Martyn soul", while saying "The Riff" "merits its title" and referring to "If Only" as "just lovely".
AllMusic's
Stephen Thomas Erlewine also gave the album a rating of four stars out of five. The
Chicago Tribune also included the album in their list of the best releases of the year. ==Track listing==
