Born in 1965 and raised in Paris, France, Pierre de Bethmann began classical piano lessons at age 6, only later discovering the world of jazz. He continued his musical and regular studies apace, graduated from ESCP in 1987 (major French graduate school of management), and studied one year at Berklee College of Music (Boston) in 1989.
He actually started working as a management consultant in 1990. Then he formed trio Prysm with Christophe Wallemme and Benjamin Henocq in 1994, and one year later he abandoned the desk to become a fulltime professional musician. From 1996 to 2001, Prysm performed over fifty concerts a year, including tours in the U.S., Japan and the Middle East, and recorded four albums on Blue Note.
