Two generations of musicians, make up an orchestra of 14 people with the same name. When, in 1991, the brothers Jan, Karol, Marcin and Mateusz recorded their first album of carols, several of the musicians of the current orchestra were not yet in the world. The programme from this album was recorded by TVP, and their carols entered the repertoire of radio stations on a permanent basis. The Pospieszalscy are a well-known brand on the Polish music scene. They pursue their own projects, from jazz to ethno to classical music. They compose for other performers, create arrangements and orchestrations of musical shows and film music.

In a concert lasting approximately 1'45 min, the ensemble performs original arrangements of Polish carols and pastorals, as well as a carol composed by the brothers, with text by x. Jan Twardowski entitled. Kolęda z wysokości.
