Klaus Mitffoch represents a pivotal name in the history of Polish rock music, known for their influential contributions to the post-punk and new wave scene of the early 1980s. The band was formed in 1979 by charismatic frontman Lech Janerka, who served as the bassist and main songwriter, along with guitarist Wiesław Mrozik, drummer Jarosław Ptasiński, and keyboardist Krzysztof Pociecha. They were later joined by lead guitarist Andrzej Pyszczek. Klaus Mitffoch's self-titled debut album, released in 1984, effectively encapsulated the angst and spirit of the times, featuring complex arrangements and intelligent lyrics that touched upon both societal norms and personal struggles within the context of Communist Poland.

The band's music, characterized by dark tonalities and evocative lyricism, resonated deeply with the youth of the period, making them one of the most acclaimed acts in Polish rock history despite their brief existence. With tracks such as "Strzeż się tych miejsc" and "Historia podwodna", Klaus Mitffoch left an indelible mark on the Polish music landscape. Their enigmatic and thought-provoking output reflected the turbulent political atmosphere and the general sentiment of disillusionment amongst the youth. Even after their disbandment in the mid-1980s, the legacy of Klaus Mitffoch continues to inspire and influence new generations of musicians and music aficionados in Poland and beyond.
