"We've changed it completely," Phil Collen tells UCR before the first show in St. Louis.

The Sheffield hard rock legends are gearing up for their summer tour with Journey by releasing new music.

We want to send you and a guest to San Antonio, Texas to experience Def Leppard, Journey, and the Steve Miller Band in concert!

Singer interrupts recording session to record impassioned video: “I would never, ever ask you for money.”

Here's why the frontman disapproves of the label.

Joe Elliott recalls the circumstances that led to their breakthrough single.

"We had this opportunity to come out all guns blazing," Joe Elliott tells UCR.

His 1977 audition started with a cover of 'Stairway to Heaven,' but it didn't go well.

He claims anyone who accuses the band of using backing tracks simply "can’t believe how good it is for real."

Guitarist Phil Collen tells UCR about the transformation and why the band was more "Duran Duran than Iron Maiden."

The anniversary box set arrives on April 26.

Four-CD / Blu-ray collection features previously unreleased demos and live footage from shows in Germany and Los Angeles.
