The son of a pharmacist mother and antiquarian father, Mathieu spent his early childhood in Fontenay sous Bois before acquainting himself with the piano. At age ten he started playing an organ - intended for use by his mother, but who never picked it up.
After two years of taking courses, he started his first musical group at age 13 with two fellow students and friends from middle school. After many years travelling the world, mostly Africa (especially Kenya), he started penning some naive, minimalistic ditties. His sketchy, intimate sound sometimes mixes African rhythms with reggae, and his influences such as the Dutch singer Dick Annegarn, with whom he toured in 1997.
His album Michel is accompanied by an amateur film made by Boogaerts himself.
His music is known for its laid-back style and many of his songs include a very light and delicate drum beat. 2005 – Plutôt tôt – Plutôt tard (Double Civil Defense by artists on the Tôt ou tard label), songs Demain demain with Justice of the Peace Nataf and Bombes 2 Bal, Na na na with Vincent Delerm, Les aspres with Dick Annegarn
