A typical guitar band whose name means "Black Cats", which played at the ZDK im. Lenina (Lenin Steelworks House of Culture) in the years 1963-1964. The band was founded by the drummer Wojciech Salamon, and his successor on drums was the multi-instrumentalist and singer Janusz Gajec.
     At first the group was based in Myślenice. Rehearsals, performances and events with the band took place there. During the holidays (July-August 1964) the band played at the "Pod Blachą" restaurant in Myślenice. Later the band's next home was the ZDK in Kraków - Nowa Huta, where its notable successes began. At concerts the band was accompanied by singers of the ZDK stage: Larysa Wdzięczkowska, Edward Strojny, Czesław Popielarczyk. From the singers' contest came the soloist of the later band Szwagry - Elżbieta Żakowicz.

      A guitar band - in my opinion - the best in Kraków and Nowa Huta at that time. Towards the end of its existence the band - the only one in Kraków - used a reverb effect on the lead guitar and the microphones, which made the instrumental sound much more attractive. In the line-up given below it existed until the autumn of 1964. Then Janusz Gajec left the band and was replaced by Mieczysław Spyrczyński. In this line-up it played for a few more months and then disbanded.
