Kazik Na Żywo, also known as KNŻ and Kaenżet, was a Polish group performing music on the border between rapcore and rock, formed in 1991 in Warsaw. The group consisted of Adam "Burza" Burzyński on guitar, Tomasz Goehs on drums, Robert "Litza" Friedrich on guitar, Michał "Kwiatek" Kwiatkowski on bass guitar, and Kazik Staszewski on vocals and guitar. Their first performance was at the music festival in Sopot, Poland, in 1992, where Staszewski sang "100 000 000", a song based on Lech Wałęsa's presidential campaign promise. Following their debut, the band released several albums, including Na Żywo and Ale W Studio (1994). In 1995, they released Porozumienie Ponad Podziałami, followed by Las Maquinas De La Muerte in 1999. The band's final concert took place on May 23, 2004, in Skaryszewski Park in Warsaw, before they went on hiatus. At the end of May 2008, the band reformed, and they released Bar La Curva / Plamy Na Słońcu in 2011. In 2015, they broke up again, but reunited in 2016 and made a single live appearance at the Cieszanów Rock Festival.
