Sweat is the third studio album by American rapper Nelly. It was intended to be released on August 17, 2004, before being delayed and released on September 13, 2004, by Universal Records. Production was handled by several producers, including Jason "Jay E" Epperson, Midi Mafia, The Neptunes, Trife, Jazze Pha, Doe and the Alchemist. Released in conjunction with Suit, Nelly intended to release a single album before conceptualizing and releasing two albums simultaneously, both which would contrast each other's themes. Nelly characterized Sweat as "more up-tempo" and "energetic" while describing Suit as more of "a grown-up and sexy vibe [...] it's more melodic".
