Hemp Gru is a team from the Warsaw Mokotow district, which dates back to the late 90s. The works of Bilon, Wilk and Żar are characterized by a distinctive and uncompromising style, given without ambiguity. The group debuted in 1998 with the compilation Hip-Hop'owy Raport z Osiedla with the song Na krawędzi. In November 2004, the first, long-awaited Hemp Gru album was released. Klucz is considered the classic of Polish hip-hop.
