Better known under the pseudonym Oldelaf, author, composer and performer Olivier Delafosse was born in Paris on May 10, 1975. Attracted to music as a child, he attended the Conservatoire and practiced several instruments, before embarking on a group adventure with Caméléon and Les Petits Humains in the late 1990s. Combining song and humor, in 2000 he joined forces with actor Frédéric Draps to form the duo Oldelaf et Monsieur D, who recorded four albums and enjoyed success without taking themselves too seriously, until their split in 2010, celebrated in a farewell concert at the Olympia in Paris. A member of the rock humor group Les Fatals Picards for one album, and author of a children's album, 2009's Bête et Méchant, which won an Académie Charles-Cros award, Oldelaf turned to his solo career in 2011, unveiling the album Le Monde Est Beau, in which tender lyrics alternate with a certain disillusioned humor. After a year of touring, symbolized by the DVD Oldelaf au Trianon (2012) and a new date at the Olympia, the author of "La Tristitude" appeared on radio and TV with Michel Drucker, and in 2014 produced the album Dimanche, financed once again by the public and produced by Jean-Louis Piérot. Oldelaf then took part in the musical Le Soldat rose and reappeared on TV alongside Dave, between two concerts on a tour that ended at the Zénith in Paris. He then teamed up with Stéphane Bern on the radio, and set to work on the album Goliath (2018), backed by a string orchestra. He postpones his tour due to arm surgery, which immobilizes him for several months, then returns to the studio for the album L'Aventure (2020), released just before the first confinement linked to the Covid-19 pandemic. He was back on the radio with Nagui and Leïla Kaddour's show, La Bande originale, where he presented a singing column, before releasing the album Saint-Valentin in 2024. The following year saw the release of Délires Chroniques, characteristic of his style that blends humor, folk, pop and rock.
