In June 2018, at the height of the Sonic Highways Tour supporting Concrete and Gold (2017), where Foo Fighters experimented with orchestral elements and guest vocals, the California band headlined Rock am Ring—one of Europe's largest rock festivals launched in 1985 at Germany's Nürburgring circuit as a platform for alternative rock emphasizing stadium sound. Their 2-hour set, captured in professional quality, embodied tour climax, where Pat Smear's guitar riffs merged with Taylor Hawkins' drum power, and covers like "Under Pressure" with a guest sparked euphoria among 80,000 under summer skies. As their last major Europe gig before hiatus, this performance underscored their veteran status, turning the circuit into a collective triumph arena.
