Jaroslav Ježek was born in 1958, studied the bassoon on the Conservatory of Music in Prague. He was a member of the Chamber Opera Prague, the State Opera House, Prague for twenty years and the Prague Castle Guard & Czech Police Symphonic Band for ten years. Until nowdays he has been member of several chamber units include the Woodwind Trio Domino that did the USA tour in 2007 with a program The Influences of the Czech folk music to European classicism. He devotes to composing and arrangement as well. 
His musical output is commonly divided into two parts. The first part of his work consists of chamber, piano and concertant compositions, created first under the influence of Stravinsky, of the Parisian Les Six and of Arnold Schönberg. Later he found his own, specific and modern expression. He also became a popular jazz composer in pre-war Czechoslovakia. He composed songs and dances for the revue plays of the Prague Free Theatre (The Ass and the Shadow, Caesar, The Headsman and the Fool e.g.) and also for the films of Voskovec and Werich (Powder and Petrol, The World Is Ours, Heave Ho!). His innovative melodies are well known in the Czech Republic to this day. Ježek was also evidently fascinated by American jazz. Between 1929 and 1936, possibly earlier, he organized and conducted an orchestra featuring his original jazz compositions and arrangements. Billed variously as "Ježek's Jazz" and "Ježkův swingband" they recorded for the Czech Ultraphon label, making some of the most original music in Europe. A few of these recordings deserve special mention. "Bugatti Step" (1930; Ultraphone A10166) is an up-tempo number for piano and jazz orchestra, enjoying enduring popularity as a hot jazz piano solo. "Teď ještě ne" (Not Yet) (1931; Ultraphon A10217) is rousing dance music in the Jean Goldkette or Coon-Sanders' Nighthawks style. "Rubbish Heap Blues" (1937; Ultraphon A11421) shows that Ježek not only listened to Duke Ellington's records, but was keeping up with Duke's very latest work. "Rubbish Heap" features a Johnny Hodges-like alto sax and a Cootie Williams-like growl trumpet, plus a three-trombone section to complement the three trumpets. Ježek's composition titled simply "Polonaisa" (1931; Ultraphon A10355) is a traditional Polonaise clothed in modern instrumentation, harmony and textures. It is as if Chopin and Gershwin had collaborated, the Polish dance rhythms mingling easily with hot syncopation. Ježek also turned the boys loose in records of his arrangements of well-known hot jazz standards, such as "Tiger Rag," "Dinah" and "Chinatown, My Chinatown." These recordings, very few of which could have survived the Nazi occupation and World War II, are almost completely unknown, at least in the U.S.A.
A seven-volume CD retrospective of Voskovec and Werich's work for the Liberated Theater (1929–1938) containing the items mentioned above and dozens of others was issued by the Czech Supraphon label in 1994 (and reissued in 2007).
