Jay-Z and Eminem to Headline Oxegen Fest

Jay-Z is adding to his list of festival appearances and will now, along with Eminem, headline Ireland's Oxegen Fest this summer. The hip-hop superstars will hit the stage for the countries largest music festival playing to an estimated 80,000 fans. Although the two previously collaborated on the track 'Renegade' off Jay's 'The Blueprint' album, it's unsure if they will hit the stage together. The Black Eyed Peas, John Mayer, and Muse have also been added to the bill.

This appearance marks the first time Em will return to the country since his sold-out shows in Ireland's Marley Park in 2004. Aside from Oxegen, the Detroit native will first hit up Scotland's T in the Park, and Switzerland's Openair Frauenfeld in July. "I'm excited to get back to Europe to rock some shows," he said in a statement. "The crowds there are always big, crazy and dedicated...it's going to be great to feel that energy again."

Penned as "Europe's greatest music festival" the three-day concert was first held in 2004. The concert takes place July 8-11 and tickets go on sale March 12. For more information visit www.oxegen.ie.
