The FLOSS Festival, formerly known as Im Fluss, transforms the Rhine bank in Kleinbasel into an open-air stage for three weeks in August. Regional and international bands perform on a floating pontoon in front of the Mittlere Brücke, while the audience listens from the riverbank and the Rhine steps. Admission to the concerts is free; a voluntary collection is taken.
