Loussier was born in 1934 in Angers, France to a banker and homemaker. He first started taking piano lessons around age ten. Soon after, he discovered the music of Bach, including pieces like "Notebook for Anna Magdalena Bach" and "Prelude in G Minor." He became entranced, often improvising naturally upon the themes in the pieces. By his teens he had moved to Paris where he studied privately with noted pianist Yves Nat, delving deeper into Bach, as well as composers like Claude Debussy, Gabriel Fauré, and Camille Saint-Saëns. He enrolled at the Conservatoire National Musique and continued to expand his skills outside of class playing jazz gigs at local bars. While at school he began to compose, and further solidified his third stream approach fusing classical with jazz.
Following his graduation, he embarked on a fruitful career as an accompanist, working with a bevy of marquee singers including Charles Aznavour, Frank Alamo, Catherine Sauvage, and others. He was able to travel and soak up the musical traditions of other parts of the world including that of the Middle East and Latin America. He also formed his own trio with bassist Pierre Michelot and drummer Christian Garros. Known for their jazz reworkings of Bach pieces, the trio debuted with a series of albums on Decca beginning with Play Bach No. 1 in 1959 and culminating in Play Bach Aux Champs Elysees in 1965. A major success for Loussier, the trio toured and recorded for 15 years, moving from Decca to Philips/Phonogram in the early '70s and selling over six million albums. The trio gained wider public recognition when their version of Bach's "Air on the G String," which was used in a series of award-winning Benson & Hedges television commercials. Along with leading his trio, Loussier began composing for film and television, issuing soundtracks for projects like 1967's The Killing Game, 1968's The Dark of the Sun, and 1969's You Only Love Once, among others.
In the early '70s, he disbanded his trio and settled in Provence, where he opened his own recording studio, Studio Miraval. In addition to producing his own projects there, Miraval has played host to a variety of artists over the years including Elton John, Sting, and Pink Floyd. Away from his trio, Loussier began to expand his musical palette, exploring electronics, funk, and Latin sounds on albums like 1979's Pulsion, and 1982's Pagan Moon. In 1985, inspired by the 300th anniversary of Bach's birth, Loussier formed a second version of his trio, again playing a mix of classical and jazz with many of the added stylistic textures he had adopted since the group's start. Working with his second trio, Loussier continued to find a receptive audience issuing albums like 1996's Jacques Loussier Plays Bach, which landed at number 33 on the Billboard Classical Albums chart.
More albums followed including 1999's Bach Book: 40th Anniversary Album and Ravel: Bolero, both of which featured his signature classical and jazz mix. In 2000, Loussier paired his trio with Turkish pianists Güher and Süher Pekinel for Take Bach. Baroque Favorites: Jazz Improvisations arrived in 2001 and peaked in the Top 50 of the Billboard Classical Albums chart. There were similarly well-regarded recordings of Beethoven, Mozart, and Chopin. In 2002, Loussier filed a lawsuit against rapper Eminem and executive producer Dr. Dre, claiming that portions of their track "Kill You" were stolen from his composition "Pulsion." The lawsuit was ultimately settled out of court. In 2009, the then-75-year-old pianist issued the trio album Plays Bach: The 50th Anniversary Recording. He then applied his distinctively cross-pollinated voice to Robert Schumann's 1838 composition with 2011's Schumann: Kinderszenen (Scenes from Childhood). Loussier suffered a stroke in 2011 and retired from performing. He died on March 5, 2019 at a hospital in Blois, in France’s Loire Valley. He was 84 years old. ~ Matt Collar, Rovi
