Ah, jazz festivals—where would Poland be without them? They might be mushrooming all over the place, but Jazz on the Oder stands out among them as one of the oldest and most respected, right up there with Warsaw's Jazz Jamboree and Kraków's All Saints' Day Jazz Festival. In its 53rd edition this year, by now Jazz on the Oder is a well-oiled machine and is considered absolutely essential to the Polish music scene. Founded back in the sixties, for a long time this festival provided one of the best shots young musicians had at early fame and recognition. See the website for the full programme, which is guaranteed to present a careful selection of the most interesting jazz acts and events from all around the world, with special care taken to include nearly every feasible jazz subgenre in existence. In other words, you can't be 100% sure you know what jazz truly is until you've experienced Jazz on the Oder.
