Muriel Dacq (real name Muriel Desclée de Maredsous) is a Belgian (Walloon) singer-songwriter, active in the 1980s in France.
In the early 1980s, Muriel Dacq released "L'Enfer àl'envers" and "Ni pourquoi ni comment". Her biggest hit was "Tropique", released in France in 1986. It reached number 6 on the SNEP singles chart and earned a Silver disc for a minimum of 200,000 copies sold. At the time, the singer was married to Alec Mansion, a member of the trio Léopold Nord & Vous which had success in 1987 with the song "C'est l'amour", produced by Dacq. She also released "Làoù ça???" in 1986, but it was unsuccessful (#42 in France). In 1995, she tried to revive her singing career recording a new album Ohé du vaisseau, and a single entitled "Un peu + d'amour", under the pseudonym of Black & Dacq.
