Antoine Christophe Agbepa Mumba, known professionally as Koffi Olomidé, is a Congolese singer-songwriter, dancer, producer, and founder of Quartier Latin International. Often referred to as the "King of Ndombolo", he is noted for his explosive high notes, deep baritone, and offbeat voice. Agbepa is considered one of the most significant figures in 20th-century Congolese and African popular music. His lyrics often explore themes of love, politics, technology, success, infidelity, religion, chicanery, and disillusionment. Through his music and stage performances, he introduced the slower style of soukous known as tcha tcho and popularized a flamboyant fashion subculture called La Sape, alongside Papa Wemba.
Emerging as a ghostwriter for various artists in the Zairean music industry, he gained prominence in 1977 with the song "Princesse ya Synza", which featured Papa Wemba and King Kester Emeneya.
