PSR - Kamil Pisarski, perhaps the most successful Polish hip-hop producer. An artist who avoids interviews and always creates in media silence, he is the author of such diamond singles as "shaman" (palchik), "bandit" (Sobel), "BMW" (Reto)... and a dozen more. The list of artists PSR works with is also impressive: Oki, Keke, Sobel, Young Age, Young Lesia, Kisa, Palych, Szpaku or the Polish version. PSR is also the author of the album "Wind Rose" with Yano from the Polish version, which received platinum album status.
