Born in 1962 in Les Abymes, Guadeloupe, Schwarz-Bart grew up in a creative family, the son of two award-winning writers, Black Guadeloupean novelist Simone Schwarz-Bart and French-Jewish author André Schwarz-Bart. As a child, he learned how to play the gwo ka drum with percussion master Anzala and became exposed to the French Antillean biguine style of music. It was around age six that he first became interested in jazz and eventually taught himself how to play guitar by playing along to records. Although music was his passion, he initially headed towards politics, graduating from the Paris Institute of Political Studies (Sciences Po) and working for a time in the French Senate. It was during this period that he picked up the tenor saxophone. At age 27, he left his job to study at Boston's Berklee School of Music. There, he embarked on a fruitful performance career, collaborating with global-minded luminaries like Roy Hargrove and D'Angelo as well as Danilo Perez, Chucho Valdes, Ari Hoenig, and many others. In 1999, Schwarz-Bart made his solo debut with Immersion, a modal jazz album featuring pianist James Hurt. There were also recordings with guitarist Fernando Huergo, Hargrove's hip-hop-influenced RH Factor, Meshell Ndegeocello, Soulive, and more.
Following his time with Hargrove, Schwarz-Bart founded his own expansive ensemble, incorporating jazz, hip-hop, and R&B with Guadeloupean gwo ka rhythmic traditions. The group released two critically-lauded albums for Universal, 2007's Soné Ka La and 2008's Abyss. In 2010, he returned with another cross-pollinated album, the Caribbean jazz- and neo-soul-infused Rise Above, which featured his wife, former Brooklyn Funk Essentials singer Stephanie McKay. In 2012, he released The Art of Dreaming, which featured his longtime quartet with pianist Baptiste Trotignon, bassist Thomas Bramerie, and drummer Hans van Oosterhout.
Jazz Racine Haiti arrived in 2014 and found the saxophonist combining his contemporary jazz with Haitian traditions, including musique rasin and ritualistic Vodou music. It featured contributions by Vodou priests, singer Errol Josué, and percussionist Gaston Bonga, along with appearances by trumpeter Etienne Charles, drummer Obed Calvaire, bassist Luques Curtis, and keyboardist Milan Milanovic. Another quartet date, Hazzan, followed in 2018 and featured Schwarz-Bart's reinterpretation of Jewish liturgical chants. In 2020, he returned to his gwo ka and Caribbean-influenced sound with Soné Ka La 2: Odyssey. Along with contributions by singer Malika Tirolien, it featured pianist Grégory Privat, bassist Reggie Washington, drummer Arnaud Dolmen, and percussionist Sonny Troupé. ~ Matt Collar, Rovi
