Double Up (Mase album)

Double Up is the second studio album by American rapper Mase. It was released on June 15, 1999, by Bad Boy Records and Arista Records. Mase reunited with many of his previous collaborators on Double Up, including Sean Combs, Ron "Amen-Ra" Lawrence, and Deric "D-Dot", Angelettie, while also bringing in new contributions from Andreao "Fanatic" Heard, Daven "Prestige" Vanderpool, Nashiem Myrick, Robert "Shim" Kirkland, Righteous Funk Boogie, Buckwild, and Mario Winans.

The album received mostly mixed reviews from music critics, with some ranking it among the best hip-hop albums of the year, while others deemed it inferior to Harlem World. Commercially, the album failed to reprise the success of his debut: it opened and peaked at number 11 on the US Billboard 200 and was certified gold by the Recording Industry Association of America (RIAA) exactly one month after its release on July 15, 1999. Two months before the release, Mase announced his retirement from rapping to become a Christian pastor. Thus, Double Up would mark his latest release until 2004's Welcome Back.
