Def Leppard Will Have New Music In The Not-Too-Distant Future

Rick Allen says Def Leppard is working on new music.
In a new interview the drummer said, “There’s always new music on the go. And I’m happy to announce that in the not-too-distant future we’ll be able to present that.”
Allen explained, “I think that’s one of the nice things about technology these days is that we can be all over the planet and still sharing ideas or coming up with new songs. So, yes, that’s a given [that there will be a new Def Leppard album].
