Bryan-Michael Paul Cox (born December 1, 1977) is an American record producer and songwriter, known for his work with artists such as Usher, Mariah Carey, Mary J. Blige, and Toni Braxton. His most notable productions are "Be Without You" for Mary J. Blige, "Burn", "Confessions Part II" and "U Got It Bad" for Usher, and "Shake It Off", "I Stay In Love" and "You Don't Know What To Do" for Mariah Carey.

While attending Kinder High School for the Performing and Visual Arts in Texas, Cox met singer Beyoncé. He began producing songs for Destiny's Child prior to their signing with Columbia Records. Cox relocated to Atlanta to pursue his professional music career in 2000, where he established a partnership with Jermaine Dupri and became in-house talent for his So So Def Recordings record label.

Cox attained a Guinness World Record for the longest consecutive period of chart success by spending over 5 consecutive years there, breaking the record that was previously held by The Beatles. In 2009, Cox was inducted into the Georgia Music Hall of Fame for his contribution to music.

Cox has said that his mother played the flute: "My mom would buy music instead of food when I was little. We would spend her entire pay check at the record store." He expressed his musical ambitions to her when he was seven years old, having written his first song when he was just six years old. Later, he enrolled in Houston's Kinder High School for the Performing and Visual Arts.

In high school, Cox met Beyoncé when he was a senior and she was a freshman. He recorded his first-ever demo tape with her. Although the two wouldn't reconnect until nearly seven years later when Bryan produced a track on Destiny's Child's Destiny Fulfilled, it was the early confirmation from Mathew Knowles that prompted Bryan to go into the music industry.

"Back then, there was three choices if you wanted to be in the music industry: live in New York, LA, or Atlanta. I enrolled in Clark Atlanta University because although my mom supported my dreams one hundred percent I had to go to college, so I chose Clark because I was just trying to get to Atlanta."

Cox began his career as an intern at Noontime Records in Atlanta, Georgia. He was discovered by his manager Chris Hicks, who was a partner in Noontime. Cox's first two hit singles as a producer were "Get Gone" & "Creep Inn" for the short-lived R&B group Ideal.

Cox contributed to Lil Bow Wow's debut album, Beware of Dog, writing the single "Puppy Love" and the Big Momma's House soundtrack. He worked with Jagged Edge's second studio album J.E. Heartbreak, contributing to songs "He Can't Love U" and "Let's Get Married". He contributed to Tamar Braxton's debut album, Tamar co-writing and producing "Get None" with musical partner Jermaine Dupri. He wrote and co-produced the second single "Just Be a Man About It" from Toni Braxton's third studio album, The Heat.
