In March 2015, at the peak of the Sonic Highways Tour, Foo Fighters—led by Dave Grohl and riding the eponymous album, where post-grunge gained a documentary hue with recordings in eight cities including Rio—headlined Rock in Rio in Rio de Janeiro, the legendary festival founded in 1985 by Roberto Medina drawing 100,000 to Cidade do Rock. Their 90-minute set, rich with Chris Shiflett's guitar solos and Taylor Hawkins' drum fills, embodied the Latin American leg's climax, where "Learn to Fly" resonated through the crowd, blending with festival euphoria under tropical skies. As a rare artifact of their global dominance, this show transformed the Brazilian arena into a space of collective unity.
