From Wikipedia
The College Dropout is the debut studio album by the American rapper Kanye West. It was released on February 10, 2004, by Roc-A-Fella Records and Def Jam Recordings. In the years leading up to its release, West had received praise for his production work for rappers such as Jay-Z and Talib Kweli, but he faced difficulty being accepted as an artist in his own right by figures in the music industry. Intent on pursuing a solo career, he signed a record deal with Roc-A-Fella and recorded the album over a period of four years, beginning in 1999.
