Antwan André Patton (born February 1, 1975), better known by his stage name Big Boi, is an American rapper, song-writer, record producer and actor, best known for being a member of American hip hop duo OutKast alongside André 3000. His work in the duo has produced six studio albums. During the duo's hiatus, he and André 3000 each announced plans to release a solo album. Big Boi's solo debut Sir Lucious Left Foot: The Son of Chico Dusty was released in July 2010 to respectable sales and critical acclaim.

Patton was born and spent the first half of his childhood in Savannah, Georgia, attending Herschel V. Jenkins High School before moving to Atlanta with his Aunt Renne. Eventually he decided to pursue his interest in music at Tri-Cities High School, a Visual and Performing Arts Magnet School.

He had a strong interest in hip-hop music, and met André "3000" Benjamin while attending Tri Cities High School in the early-1990s. The two eventually joined forces as OutKast and signed with LaFace Records.

Patrick "Sleepy" Brown (born January 24, 1970 in Savannah, Georgia) is an R&B singer-songwriter, and record producer. He is one-third of the successful Atlanta-based production team of Organized Noize, which has created hits for acts such as OutKast, Goodie Mob, and TLC. TLC's "Waterfalls", penned by Brown and Organized Noize's Rico Wade and Ray Murray, was a #1 hit single on Billboard's Hot 100 in the summer of 1995.

Patrick Brown was born on January 24, 1970. In his early days, Brown was fascinated with music and often used to carry around an old four-track machine and small keyboard everywhere he went. That earnestness appealed to Wade and Murray when they first met Brown around 1990. A talented keyboardist and advocate for live instrumentation, Brown developed into a multi-instrumentalist, mastering various types of synthesizers and electric pianos; however, his inclination for using samplers and drum machines always kept him rooted in hip hop. A personal milestone for Brown, however, was the opportunity to work with funk legend Curtis Mayfield in 1996, on his final album New World Order. In the early 2000s, Brown gradually ascended from behind the studio boards into the artist spotlight.
