PRIME Summer Open Air Festival Bielefeld

The 2025 edition of the PRIME Summer Open Air established the annual festival format as a summer highlight of Bielefeld's Prime club. With a focus on Eastern European pop and dance music, the open-air event caters to a clearly defined audience—the club's regular community—and complements it with a larger festival setting featuring a stage show and food truck offerings.

Bielefeld, as the largest city in East Westphalia-Lippe, is an important hub for events with an international focus. The open-air format has gained importance in recent years as it transfers indoor club experiences to the summer and appeals to larger audiences.
