Michel Léon Chapuis (French pronunciation: [miʃɛl ʃapɥi]) (15 January 1930 – 12 November 2017) was a French classical organist and pedagogue. He was especially known as an interpreter of the French and the German Baroque masters and dedicated to historically informed performances.
Jacques Loussier (26 October 1934 – 5 March 2019) was a French pianist and composer. He arranged jazz interpretations of many of the works of Johann Sebastian Bach, such as the Goldberg Variations. The Jacques Loussier Trio, founded in 1959, played more than 3,000 concerts and sold more than 7 million recordings—mostly in the Bach series. Loussier composed film scores and a number of classical pieces, including a Mass, a ballet, and violin concertos. His style is described as third stream, a synthesis of jazz and classical music, with an emphasis on improvisation.
