Olivier was born in Washington DC of Haitian and Cameroon heritage, but spent most of his childhood studying in the remote countryside of the UK. His boarding school experience not only developed his appreciation for other cultures but musically he grew-up hearing beyond the excepted genres of a kid from the Nation’s Capital. At age 15 Olivier’s CD and sometimes cassette collection would range from hip hop, RnB to Garage and British rock.

Olivier remained in the UK and completed a Bio Science Degree in Oxford but couldn’t suppress his real passion for music. After graduation, he began a ‘Jekyll and Hyde’ life. A scientist by day; recording artist by night.

​

In 2006 he released his first album titled “kilowatt”, which put the artist known as ‘Olivier Daysoul’ on the map within the underground electro-hip-hop scene. Simultaneously, Olivier began receiving numerous requests from producers to feature as a vocalist.
He went on to receive significant international attention for his work as a featured singer/songwriter. This momentum pushed Olivier in 2010 to take the leap and pursue music full time. He worked and toured worldwide with various artists including Hudson Mohawke, Oddisee, the C2C Dj’s, and many more. Despite all of this, Olivier felt something was missing…A true reflection of his own voice and sound.

A hiatus from feature recordings and some deep introspection found Olivier discovering his love for blues, rock and funk.  Many late-night guitar sessions resulted in new soundscapes. A new chapter was opening. The former ‘Daysoul’ moniker exchanged for his original birth name ‘St. Louis’. Producing and writing all his own music and playing his own instrumentation; Olivier St. Louis was embarking on a new road.
After a successful UK Tour with Laura Mvula, Olivier is getting ready to join Germany’s most prolific band at the moment, AnnenMayKantereit for another Tour in spring 2017 and he surely won’t come without his upcoming release “Ever since the fall EP”, out on Jakarta Records in February 2017.

When asked his thoughts on his artistry he states:
„no punches pulled …no compromises … just me”.
