DEF LEPPARD kicks off their summer tour next week in Belfast, N. Ireland. Today until June 7th the band will be releasing behind the scenes rehearsal and performance videos shot last month. The first clip can be seen below:

Def Leppard will release their new live album, Mirrorball - Live & More on June 7th in North America exclusively at Walmart and Sam's Club stores. The Walmart pre-order has been launched at this location.

Mirrorball - Live & More will see a European release via Frontiers Records on the following dates:

June

17 - Germany, Austria and Switzerland
20 - the rest of Europe excluding France
23 - France

The Mirrorball - Live & More booklet contains 16 pages with live photos by Ash Newell. Many photos have already been seen in the Shots From The Sparkle Tour coffee table books. The credits state that the live songs were “recorded at various points around the world, in the not too distant past” during the Sparkle Lounge tour 2008/2009. The mirror ball graphics on the discs all seem to be based on the same art that was used for the 'C’mon C’mon' promotional CDs in 2008.

DefLeppardNow.com webmaster weighs in on the audio portion of Mirror Ball - Live & More:

"The album starts with a bang, straight into the intro to 'Rock! Rock! (Till You Drop)'; there’s not even a fade-in of the audience. The songs are presented as one show (no fade-outs/fade-ins between songs), but even if you didn’t know that the songs come from various shows, Joe (Elliott) gives it away by mentioning various places (Salt Lake City, California, Las Vegas and San Antonio). The only fades are between 'Rock On' and 'Two Steps Behind' (because that’s where disc 1 and disc 2 switch) and between 'Let’s Get Rocked' and 'Action'. This is because 'Action' and 'Bad Actress' (both from the 2008 Islington club show, it seems) are presented as 'bonus live tracks'. No big surprises in the songs, they all have the live quality we’re used to getting from the band."

"As for the new songs… 'Undefeated' is written by Joe, 'Kings Of The World' is written by Sav and 'It’s All About Believin' is written by Phil and CJ Vanston. Both Vivian and Rick do not have any writing credits on the entire album."

And now the video portion:

"Next to the promo videos for 'Nine Lives' and 'C’mon C’mon', the DVD also contains a 50-minute documentary, which is a collection of videos shot with a handheld camera (I think) and some professionally shot live footage. The main menu of the DVD lets you choose from the following chapters: - 'Rock! Rock! (Till You Drop)' (Live)
- Rick Allen returns to Donington
- Quebec, Canada
- 2009 Country Music Awards
- 'Hysteria' (Live)
- Backstage at Download
- 'Armageddon It' (Live)
- Japan/Australia tour
- 'Pour Some Sugar On Me' (Live)
- Making of The Mirror Ball (sic)

'Rock! Rock! (Till You Drop)' was shot somewhere in North America, the other three live tracks are from the 2009 Download festival. Although the whole is brought as a documentary, there is no voice-over or host and the non-live footage is a compilation of all kinds of backstage/studio material from 2008/2009/2010."

Def Leppard will return to North American stages with special guests HEART on a 48-city summer tour kicking off on June 15th in West Palm Beach, Florida. Check out the complete itinerary here.
