Led Zeppelin fans can tuck a photo book filled with great pictures of the band into their pockets now, thanks to the 'Live Dreams' photo gallery iTunes application.

The "app," as these programs are known, is the portable, digitally advanced version of photographer Laurance Ratner's collection 'Led Zeppelin - Live Dreams, a Photographer's Visual History of the Led Zeppelin Live Experience, 1972-1977.'

As you can guess by the title, the book combines Ratner's wonderful photos and memories of life on the road with perhaps rock's most popular band ever.

As you scroll through hundreds of high-quality pictures of Robert Plant, Jimmy Page and company in action, Ratner occasionally pops in with informative text, or sometimes audio clips, of his behind-the-scenes stories from each era. These are great stories that add depth and context to the photos.

There are also photo sections and essays dedicated to regular features of Zeppelin's concerts, such as the acoustic segment or the wide-roaming 'Dazed and Confused' marathons the band engaged in regularly. You can even find information on how to purchase the photographs in high-quality archival form.

In short, this is a great application for any Led Zeppelin fan with an iPod. It's like having a great big biographical photo book ready to enjoy anywhere at a moment's notice. Best of all, and yes, we tested this, you can play Zep songs from your iTunes app while scrolling through the photos, creating kind of a flip-book concert experience while you're in line at the grocery store.
