Kaliber 44 is a hip hop band formed at the end of 1993 in Katowice, Poland. The group is dubbed the most influential Polish hip hop band, while
their so-called Hardcore Psycho Rap style is the most prominent. It was originally thought that the name of the group came from a gun, but
later members revealed that it should be explained differently: first part of the name comes from the calibre of problems the group sings about.
The number 44 is a reference to a prophetic poem Dziady written by Polish poet Adam Mickiewicz.
