Oxegen 2005

Sunday night headliners Foo Fighters,[3][4] as well as Ian Brown,[5] The Prodigy,[6] The Frames,[7] Keane,[8] and The Killers[9] were some of the first acts to be announced for the festival.

Also playing were Saturday night headliners Green Day,[10] New Order,[11] James Brown, Queens of the Stone Age,[12] Feeder, Kasabian,[13] Nine Black Alps, The Departure, Razorlight, LCD Soundsystem,[14] Echo & the Bunnymen, The La's, The Revs, Snoop Dogg and The Futureheads[15] are some of the acts that performed at the festival.

Kaiser Chiefs made their Oxegen debut as the third act on the Main Stage on the Saturday, a feat they would surpass on the Sunday of the following year when they were third headliners.

They performed much of their own material and also previous songs by Soundgarden ("Spoonman" and "Black Hole Sun") and Rage Against the Machine ("Killing in the Name").

The band minus Chris Cornell went on to headline Oxegen 2008 with Zack de la Rocha as the reformed Rage Against the Machine, with "Killing in the Name" performed in its original style.

[17] The scheduled appearance of Bright Eyes in the Green Room on the Saturday was cancelled at the last minute; they were replaced on the bill by Irish band 66e who were asked to step in on that same afternoon.

Dublin Bus operated a shuttle service to Punchestown from Parnell Square West with buses departing every 20 minutes.
