Saw the Foo Fighters absolutely destroy The Red Hot Chili Peppers in Phoenix a few years back. Ever since I have not been a Chili Peppers fan at all. Waited months for the show and then was greatly disappointed except for the Foo Fighters. Dave Grohl rocked!
'they blew'em off the stage'
what concerts have you attended, where the warm up act blew the headliners away.....my examples...brownville station upstaging zz top to the point where people where chanting 'brownsville station!' during the littl ol' band from texas' set.....another..t.rex upstaging lynyrd skynyrd(yes there really was such a show), and the grass roots upstaging cream.
