Calvin Richardson was born in Monroe, North Carolina and was the first of nine kids. His mother sang in a local gospel group, and exposed Calvin to a wide variety of gospel music as a child. It was while Calvin was singing on the gospel circuit that he met and befriended the Hailey brothers Cedric "K-Ci" and Joel "JoJo."
When Calvin saw the success of K-Ci & JoJo's group Jodeci, he formed his own group called Undacova. While the group had a song "Love Slave" on the New Jersey Drive soundtrack in 1995, they never made an album. The group folded and Calvin Richardson took the opportunity to get a deal on Universal Records.
While at Universal, Calvin Richardson released his album Country Boy in 1999. The album featured appearances by K-Ci, Monfia, and Chico DeBarge but failed to move a lot of copies.
After the album's release, Calvin immediately began work on a second album. However, the album was put on hold as he was invited by Angie Stone to collaborate with her on her album, Mahogany Soul. Calvin appeared with Angie on her track "More Than A Woman." Calvin.
Calvin put out his completed sophomore album in 2003 at Hollywood Records. The album was titled 2:35PM, after the time that Calvin's child was born. The reason that Calvin named the album as such was because, his girl gave birth to their son, Souljah, while Calvin was working on completing the album. With the events so intertwined, the title seemed fitting for his new album. Calvin Richardson scored a respectable commercial success with the album, selling over 250,000 copies.
In 2008, Calvin released his third album, When Love Comes.
