Johnny Cash's legacy will continue to live on in a new book and music collection. 'LIFE Unseen: Johnny Cash -- An Illustrated Biography' will be released on Aug.13 in honor of the 10th anniversary of his death.

The 192-page book will include rare and never-before-seen photos of the Man in Black from the Sony archives, as well as interviews with Cash and his family, and new memories shared by his children, Rosanne Cash and John Carter Cash.

"I'd seen a lot of these photographs, but the ones I hadn't seen before were really moving to me," Rosanne Cash tells Nashville's Tennessean. "They weren't just kind of stock Johnny Cash pictures, but showed some side of him, some depth, that hadn't really been captured before."

Legacy Records is releasing a new music collection in conjunction with the book. 'LIFE Unheard: Johnny Cash,' includes solo acoustic songs recorded at his House of Cash studio at his home in Hendersonville, Tenn., as well as live songs from the White House and Newport Folk Festival. The 12-song album also features a previously unreleased studio version of Ben Dewberry's 'Final Run,' and 'Movin' Up,' both recorded for Cash's 1981 made-for-TV movie, 'The Pride of Jesse Hallam.'

Cash, who passed away on Sept. 12, 2003, from complications from diabetes, is also being remembered on the 10th anniversary of his passing with a special Johnny Cash Limited Edition Forever Stamp by the United States Postal Service.
