Django Reinhardt in the context of "George Harrison"

Gypsy jazz (also known as sinti jazz, gypsy swing, jazz manouche or hot club-style jazz) is a musical idiom inspired by the Romani jazz guitarist Jean "Django" Reinhardt (1910–1953), in conjunction with the French jazz violinist Stéphane Grappelli (1908–1997), as expressed by their group the Quintette du Hot Club de France. The style has its origins in France and the Manouche clan of Romanis, and has remained popular amongst this clan. Gypsy jazz is often called by the French name jazz manouche, or alternatively, manouche jazz in English-language sources.

Reinhardt was foremost among a group of gypsy guitarists working in Paris from the 1930s to the 1950s. The group included the brothers Baro, Sarane, and Matelo Ferret and Reinhardt's brother Joseph "Nin-Nin" Reinhardt.

Stéphane Grappelli (French pronunciation: [stefan ɡʁapɛli]; 26 January 1908 – 1 December 1997) was a French jazz violinist. He is best known as a founder of the Quintette du Hot Club de France with guitarist Django Reinhardt in 1934. It was one of the first all-string jazz bands. He has been called "the grandfather of jazz violinists" and continued playing concerts around the world well into his eighties.

For the first three decades of his career, he was billed using a gallicised spelling of his last name, Grappelly, reverting to the Italian spelling Grappelli in 1969. The latter is used when referring to the violinist, including reissues of his early work.

The Quintette du Hot Club de France ("The Quintet of the Hot Club of France"), often abbreviated "QdHCdF" or "QHCF", was a jazz group founded in France in 1934 by the guitarist Django Reinhardt and the violinist Stéphane Grappelli. It was active in one form or another until 1948.

One of the earliest and most significant continental jazz groups in Europe, the Quintette was described by critic Thom Jurek as "one of the most original bands in the history of recorded jazz." In contrast with the "New Orleans Sound" of groups like Louis Armstrong and His Hot Five and Hot Seven, the group (at least in its early incarnations) featured an (at that time, novel) "all strings" lineup with the lead parts taken by virtuoso acoustic guitar and violin, the bass part on double bass in place of tuba or sousaphone, and the rhythm and accompanying chords supplied by additional guitarists, with no drummer.

Pierre Joseph "Baro" Ferret (1908–1976) was a gypsy jazz guitarist and composer. He was known by his Romani nickname "Baro," which meant "Big One" or even "King" in Romany. Through his brother Jean "Matelo" Ferret, Baro met Django Reinhardt, and the two men became both friends and rivals. From 1931, the Ferret brothers, along with their third brother Etienne "Sarane" Ferret, and cousin René "Challain" Ferret, were favorite sidemen of Reinhardt. Baro recorded around 80 sides with Reinhardt. The Ferret brothers played with musicians including Didi Duprat.

Baro retired as a full-time musician during World War II and devoted himself to running bars and to black market businesses during the German occupation of Paris, an activity he continued into the early 1970s.

Étienne "Sarane" Ferret (1912–1970) (surname also later spelled Ferré on occasion) was a French musette and gypsy jazz guitarist and composer, a contemporary and musical associate of Django Reinhardt, and the brother of noted Romani guitar players Baro and Matelo Ferret. He recorded with his own quintet in Paris in the 1940s and continued performing there, with occasional recording sessions, until his death in 1970.

Jean Pierre "Matelo" Ferret (1918 – 24 January 1989) (also spelled Matelot, Matlo and Matlow, surname also later spelled Ferré on occasion) was a French musette and gypsy jazz guitarist and composer. He was an associate of Django Reinhardt and the youngest brother of guitarists Baro and Sarane Ferret. He recorded with his own sextet in Paris in the 1940s and continued performing there, with occasional recording sessions, until his death in 1989. He was noted for a musical style that incorporated Russian and Hungarian influences and lived long enough to see a resurgence of interest in gypsy jazz in which he was recognised as one of the great surviving players of the genre. Two of his sons, Boulou and Elios Ferré, continue to play a more modern and individualistic form of gypsy jazz-based guitar music in Paris.

Joseph "Nin-Nin" Reinhardt (1 March 1912 – 7 February 1982) was the younger brother of guitarist Django Reinhardt and played rhythm guitar on most of Django's pre-war recordings, especially those with the Quintette du Hot Club de France between 1934 and 1939. He was a pioneer of the amplified jazz guitar in France and performed for years on a home-made instrument of his own design.

Marion Walter Jacobs (May 1, 1930 – February 15, 1968), known as Little Walter, was an American blues musician, singer, and songwriter. His revolutionary approach to the harmonica had a strong impact on the succeeding generations, earning him comparisons to such seminal artists as Django Reinhardt, Charlie Parker and Jimi Hendrix. His virtuosity and musical innovations fundamentally altered many listeners' expectations of what was possible on blues harmonica. He was inducted into The Rock and Roll Hall of Fame in 2008, the first and, to date, only artist to be inducted specifically as a harmonica player.
