Oleg Khromushin was born in 1927. He is the author of operas, operettes, musicles, symphony scores. Khromushin is glorious for his vocal-orchestral compositions, especially connected with the children's choir. Remember his numerous piexes for chamber cast, so as the series of his educational manuals “I want to Study Jazz”. That happened to be the point, where the composer's passions for chamber and jazzmusic crossed. This collision gave birth to the Suite “5+3”. It was composed in 1984 for the Petersburg Brass quintet, meanwhile consisting of three movements. Hence its title. The composer resorts to jazz musical devices and rhythms, leaving the classical musical form and polyphonic devices.
