Grammo Musik Festival Leichlingen

The 17th edition of the Grammo Musik Festival 2025 took place on the Pentecost weekend, from June 6 to 9, 2025, in Leichlingen's Alter Stadtpark. As in previous years, the organizer was GrammoEvents. Admission was free.

The program structure followed the classic pattern: opening on Friday evening, full day programs from 2:00 PM Saturday through Whit Monday, multiple stages, a large children's area, beer garden, and barbecue stands. Several thousand visitors from Leichlingen, Solingen, Leverkusen, and the wider Bergisches Land region passed through the park over the four days. Specific band lists for 2025 were documented via GrammoEvents' social media channels (Facebook, Instagram, YouTube) and local event portals like bergisch-live.de; a central online documentation of all acts from past editions is not available.
