Foo Fighters performed at Summer Sonic Festival in Japan, and during their set, they brought out a surprise guest who was also on the lineup: Rick Astley. “This is fuckin’ crazy,” said Dave Grohl. “I just met him two minutes ago.” And then, Astley screamed to the crowd, “COME ON YOU MOTHERFUCKERS!” (Really.) Then, Foo Fighters backed up Astley in a beefed up cover of “Never Gonna Give You Up.” Watch it happen below via CoS, and check out the selfie Grohl took with his “new best friend.” Foo Fighters’ new album Concrete and Gold is out September 15 via Roswell/RCA. Yesterday, St. Vincent debuted a new song at the same festival.
