The Moody Blues have put together a 17-disc career-retrospective box set.

Timeless Flight: The Ultimate Moody Blues - The Ultimate Journey comes in an LP-sized hard-back slipcase and contains 11 remastered CDs featuring key album tracks, previously unreleased mixes, out-takes and complete live concerts. There are also three DVDs of rare TV performances from around the world, promotional videos and the previously unreleased 1970 concert from the Olympia in Paris. And three more audio DVDs contain the long-deleted 5.1 Surround Sound mixes of the albums Days of Future Passed, On the Threshold of a Dream, To Our Children's Children's Children, A Question of Balance, Every Good Boy Deserves Favour and Seventh Sojourn.

Extras include a 120-page hard-back book with rare and previously unseen photos, and a replica full-color tour poster and discography. No word on a release date, but it'll be out this year.
