Following the success of "Written in the Stars" as the album's North American lead single, it was announced that Disc-Overy would receive a United States release with a revised track list. The tracks "Obsession", "Invincible" featuring Kelly Rowland, and "Just A Little" featuring the Roc Nation artist Range were removed from the American track list, while new collaborations with Wiz Khalifa, Bei Maejor and Ester Dean were added. New production contributions came from Boi-1da and Stargate. The album was released in the United States on 17 May 2011. The three new tracks were later released in the United Kingdom on a deluxe edition of Disc-Overy, made available on 20 June 2011.
Discussing Disc-Overy, Tinie Tempah said, "If you've heard Pass Out and Frisky and think you know what to expect, you're wrong. I wanted this album to be really raw, not only in terms of the production but the guests. I was only interested in working with people I really respect and who I'm a fan of." He also said, "I met Ellie Goulding very early on, we swapped numbers and after that we started living very parallel worlds; the same festivals, interviews and so on. It made total sense to have her on the album."
