It’ll be a stage full of stars in Hamburg on July 6, when Coldplay, The Chainsmokers, Ellie Goulding, and Herbert Grönemeyer headline the Global Citizen Festival Hamburg, the international advocacy organization announced Tuesday.

The artists will perform at the free-ticketed concert on the eve of the 2017 G20 Summit, which will gather world leaders to discuss Global Goals for Sustainable Development.

9,000 free tickets will be given out to fans who demonstrate a passion for activism. In addition to enjoying the music, concert-goers, or Global Citizens, will meet in Hamburg prior to the summit to demand that the leaders attending the summit agree to address issues of education, health, development, and the refugee crisis.

“It is truly inspiring to see so many people come together and take action, participating in these essential conversations, and holding world leaders to account,” Goulding said in a statement.

This will be the first European Global Citizen Festival, but the organization has held several in the U.S. in previous years, including 2016’s in New York, which Goulding also headlined, alongside Rihanna and Kendrick Lamar. The fest also took place in India in November.
