Ryszard Henryk Riedel was the original lead singer of blues-rock band Dżem. He is often regarded as one of the most popular and well known Silesian vocalist, along with an occasional collaborator Czesław Niemen. Riedel's legacy is remembered by an annual festival, bearing his name, held in his home town of Chorzów, which was moved from Tychy in 2009. He has become one of the most powerful vocalist of Polish music just after Czesław Niemen.

Tychy is a city in Silesia in southern Poland, approximately 20 kilometres (12 mi) south of Katowice. Situated on the southern edge of the Upper Silesian industrial district, the city borders Katowice to the north, Mikołów to the west, Bieruń to the east and Kobiór to the south. The Gostynia river, a tributary of the Vistula, flows through Tychy.
