Rawa Blues, held mostly in Katowice’s Spodek arena, is described as the world’s largest indoor blues festival. Founded in 1981, it has showcased an impressive roster of international and Polish blues artists over more than four decades, from genre legends to contemporary innovators. The event typically combines a large main-stage concert with a side stage for emerging acts and a strong community of long-time blues aficionados. Beyond its musical function, Rawa Blues has helped build a dedicated blues scene in Poland, inspiring clubs, bands and festivals elsewhere. The festival’s history is closely tied to the transformation of Katowice from an industrial centre into a cultural city and has been recognised by international blues organisations.
