The two-CD set is comprised of two hours of music, from the singer’s historic 1985 tour of the former Soviet Union, which has never been released to the public.
The album was produced by Denver’s friend, seven-time Grammy Award-winner Roger Nichols.
Denver performed 11 concerts at various venues throughout the Soviet Union and each performance was recorded on a custom digital recorder.
The recordings were rediscovered in 2002 and have been restored, remixed and mastered for the new CD set.
Many of Denver’s greatest hits are on the album, along with some lesser-known gems.
A highlight is the singer performing "Annie's Song" in Russian.
The CD set is slated for release on Oct. 25 by AAO Music, Inc., in conjunction with John's brother, Ron Deutschendorf, the record label said.
"It is always an exciting experience to take part in the production of what will be a classic album," said Peter G. Kuys, chairman of AAO Music. "This record showcases John's tremendous talent; and it is an honor for AAO Music to take part in this album."
