[1] Founded during the period of Stalinism, when jazz music, regarded as a synonymous with the "reactionary American culture", was officially banned by the then communist authorities, Melomani were forced to conduct underground activities until 1955.

This stance of the government was disliked among rebellious individuals and groups of the Polish youth (among them Leopold Tyrmand), who went underground to keep on playing thebanned music (hence, the period of late 1940s and early 1950s is called the catacombs).

Initially, Melomani played to a very limited audience, but starting since the mid-1950s, they expanded their base, and were invited to several festivals, such as legendary "Jam Session 1", which took place in Sopot in 1955, eventually becoming the most popular jazz group in Poland.

[2] The group existed until early 1958 when, following the so-called thaw of some rules of the system (see: Polish October), jazz triumphantly returned to main venues of the country, and was played even in concert halls, which had been unheard of before.

"[5] After the break-up Matuszkiewicz became a successful composer of soundtracks of several Polish movies, Sobociński went on to become a famous cinematographer, and other members of the ensemble created their own bands, such as the Andrzej Trzaskowski Quintet.
