Klub Szyderców Bis is a musical literary cabaret, active in Poznan since 2015. The formation was born on the occasion of Evenings with Indifferent Song, which are held periodically in Poznan's Jeżyce district. Sniffers refers to the style and atmosphere of the cabarets of the interwar period, and the name itself is a reference to the cabaret Klub Szyderców, which was established in 1932 in Poznan in the cafe Pod Kaktusem at Plac Wolności. The contemporary Klub Szyderców Bis and their songs can be heard on Poznan and national radio stations (Radio Poznan, Radio Emmaus, Polish Radio “Trójka”, Radio Krakow). They are winners of, among others, the All-Poland Cabaret Song Festival OSPA in Ostrołęka, the song competition as part of the PAKA festival in Cracow, Stacja Kutno, Mulatki in Elk, the Stolica Festival or Fermenty in Bielsko-Biała.
