"Undefeated" is one of three new tracks that will appear on Leppard's first-ever live album, believe it or not, which is expected to be released in the first week of June, but you can hear the new track now!

Joe Elliot describes "Undefeated" as "a foot-stomping, air-pumping rock anthem...with big tribal drums and huge guitars and a very huge vocal chorus."  He said that, since the track is called "Undefeated," it has "a very uplifting vibe," and compared to previous Def Leppard releases, the song is like "a hybrid of 'Hysteria' and 'Animal,' done in 2011."

Def Leppard is touring North America with HEART starting June 15th in West Palm Beach, Florida.  All the dates are on the band's website.
