Grace was born in a little cabin in the forest in Nova Scotia, Canada. She grew up traveling on buses because her parents were musicians and part of the peace and love movement; occasionally, Emmylou Harris watched over her while her parents were performing.
When she was seven years old, she moved to Kenya, where her mother was engaged in a humanitarian mission. As she grew older, she lived in and travelled to many places - Senegal, Ethiopia, France, India, Jamaïca... - and has more recently settled in Paris, California, and New York. She calls herself a "nomad" because she traveled extensively in Africa, India, Europe and South America.
She currently resides in the South of France, Miami, and New York.
Grace's career started in French underground venues (New Morning, Réservoir, la Scène Bastille, la Bellevilloise...). After having opened shows for the likes of James Blunt or Just Jack, Grace gained public notoriety with the interpretation of her single Imagine One Day for the World Music Day, which was broadcast by France 2, a major French TV channel. Other TV appearances include the famous French musical show Taratata, where she sang Stevie Wonder's I Wish with Amadou & Mariam. She toured extensively across France between 2008 and 2009, ending the tour with a packed Bataclan, in Paris.
Grace then travelled for a year between the USA, Brazil, and the South of France to work on her second album. On July 14, 2011, she participated in an event organized by the French anti-racist NGO SOS Racisme, in front of more than 500,000 spectators, where she interpreted a duo with the singer Jehro (Master Blaster).
