Festiwal Muzyczny im. Ryśka Riedla „Ku Przestrodze”

This Polish rock music festival began in Tychy, in Silesia, at the Paprocany recreation area, before later moving to Chorzów. It originally bore the name of singer Ryszard Riedel, frontman of the cult band Dżem who died in 1994, honoring his struggle with addiction. Renamed simply "Ku Przestrodze" ("As a Warning") after his name was withdrawn in 2015 at the family's request, the event paired rock concerts with a prevention message aimed at young people.
