After 16 years since the release of De Luxe album we have seen another De Mono album with new material. Who creates De Mono AD 2017? Kościkiewicz – we already know. But there are also old and good friends: Robert Chojnacki and his saxophone, playing keyboard instruments Wojtek Wójcicki and holding it all in the rhythm of Darek Krupicz. The group’s bassist, already a good few years, is Łukasz Przesmycki, just as good at punk and funk. The most recent person in the band is Tomasz Korpanty – vocalist.
