The Odd Couple is the second studio album by Gnarls Barkley, released digitally on March 18 and physically on March 25, 2008. Due to an early leak of the album over the Internet in early March 2008, the duo decided to push up the release from April 8. The album was released to the iTunes Store and Amazon MP3 on March 18.
As of October 2010 the album has sold 250,000 copies in United States according to Nielsen SoundScan.[14]
In late January, an assumed leaked track appeared on several music blogs. "Run (I'm a Natural Disaster)", the previously unknown song, was given positive reviews from most music outlets.[15] "Run" was released as the album's first single as a digital download in the US on February 5, 2008. Despite "Run (I'm a Natural Disaster)" being the lead single at the time, "Going On" was the highest-charting album track on iTunes having made it as high as number 23 on the Top 100 chart as of March 25, subsequently debuting at number 88 on the Billboard Hot 100.[16] The song was then released as the second single from the album, and the song's video premiered on March 20, 2008. In March 2008, the album's third single, "Who's Gonna Save My Soul" was premiered by hip hop band The Roots' drummer Questlove through a video uploaded to YouTube.[17] The album also features Josh Klinghoffer, a touring musician for the band since 2006 and who would a year following the album's release join the Red Hot Chili Peppers as their guitarist.
An early leak of the album over the Internet in early March, 2008, prompted the duo to push the release of the album from April 8. Digital versions of The Odd Couple were released to the iTunes Store and Amazon MP3 on March 18.[18] Physical copies of the album were slated for March 25; however, some copies hit independent record stores on March 18. The album was released in the United Kingdom on March 31, 2008. An instrumental reverse edition of the album, retitled elpuoc ddo eht, was released on April 17, 2008. The entire album is fused into one 38:44 track played completely in reverse, starting with the album's last song and ending with the album's first. This unorthodox edition was released officially by Danger Mouse and is legally available as a second disc on the vinyl edition of the album.
