His father was a tailor and stylist and with his uncles and aunts promoted a line of clothing unique to Marka ethnics, part of West Africa's Mandinka people.
During the nights, he used to perform at various clubs of Abidjan with musicians, most notably the famous band Super Mandé and its star artist Abdoulaye Diabaté.
In later years, he was cut off from arts and had a very tough time returning to the clubs singing covers of classics from Salif Keita, Mory Kanté and others.
In 2007, journalist David Commeillas ran a reportage on Ouagadougou music and mentioning Démé at length which encouraged him to release his debut studio album at age 46 featuring best of his materials in folk and blues, romantic mandinka tunes influenced at times with Latin salsa and flamenco sounds using Dyula language, a Mande language used in Burkina Faso, Ivory Coast and Mali.
In addition to France, Démé also performed in other world music venues in UK, Germany and throughout Europe, releasing his second album Deli in 2010 also on Chapa Blues Records.
