In July 2007, at the global Live Earth concert in Wembley Stadium—Al Gore's initiative against climate crisis involving 9 stadiums and 2 billion TV viewers—Foo Fighters, the California rock band whose album In Your Honor (2005) with its dual acoustic/hard-rock approach solidified post-grunge giant status, performed before 80,000 in London. Their 45-minute set, with Pat Smear's guitar riffs and Taylor Hawkins' drum power, embodied the day's climax, fusing stadium anthems like "Times Like These" and "All My Life" with improvisational jams to spark euphoria and reinforce their environmental message. As part of the worldwide action, this performance turned Wembley into an arena of unity.
