Country Grammar is the debut studio album by American rapper and singer Nelly. It was released on June 27, 2000, by Universal Records. The production on the album was handled by Jason "Jay E" Epperson, with additional production by C-Love, Kevin Law, City Spud, Steve "Blast" Wills and Basement Beats. Nelly contributed to all lyrics on the album, with Epperson and City Spud also contributing. With the album's release, Nelly and his "St. Lunatics" crew cemented the St. Louis sound firmly amongst other southern hip hop artists in the year 2000, such as Juvenile, Trina, Ludacris, OutKast, Three 6 Mafia and UGK. Country Grammar also introduced the world to Nelly's unique musical style of pop-rap and radio "singalongs" with a Missouri twang. It was supported by four successful singles: "Country Grammar ", "E.I.", "Ride wit Me" and "Batter Up". Its lead single, "Country Grammar ", peaked at number 7 on the Billboard Hot 100 and UK Singles Chart. Its second single "E.I." peaked at number 16 on the Hot 100, number 12 on the UK Singles Chart and number 11 on the ARIA Singles Chart. "Ride wit Me" peaked within the top five on the Hot 100, ARIA Singles Chart, Irish Singles Chart and UK Singles Chart. The album's fourth and final single, "Batter Up" featuring St. Lunatics members Murphy Lee and Ali, achieved moderate chart success.
