An extreme makeover of the Moody Blues' Classic 7 albums is in the works for a September release in the United States and elsewhere.
The extensive re-do encompasses not only long-planned surround-sound mixes but also loads of previously unreleased material, including a 1969 concert that will be released separately.
Each of the albums--Days of Future Passed in deluxe packaging, as well as In Search of the Lost Chord, 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--will be reissued as a two-disc set, said Andy Street, head of catalog development at Universal Music's UK offices.
Disc 1 will contain a remastered stereo mix of each album--except Lost Chord; see below--in standard CD format and a 5.1-surround mix in the SACD format, which is playable only on compatible players.
"With the advent of SACD and the possibilities afforded by 5.1 surround audio, the time is right for the Moody Blues' catalog to be considered for such treatment," Street said from his London office. "Always at the forefront of technology and groundbreaking recordings, the Moody Blues' albums were all mixed in Quadraphonic sound by [producer] Tony Clarke and [engineer] Derek Varnals in 1972 at Decca Studios in West Hampstead. These original multi-channel mixes were used utilizing Decca's unique reverberation chamber and equipment, which gave the Moody Blues' albums their distinctive quality. Therefore, these Quadraphonic mixes have been used for the 5.1 Surround masters.
" In Search of the Lost Chord was not mixed in Quadraphonic sound at the time due to the absence of all of the multitrack tapes, a situation verified by an exhaustive search through Decca vaults and at Threshold. Therefore this album will be presented as a high-quality SACD hybrid stereo disc mastered from the original Decca master tapes at 96kHz 24-bit. Finally, all of these SACDs will also be able to be played on conventional CD players in stereo."
Disc 2 will contains rarities, B-sides and previously unreleased BBC sessions, he said.
"The discovery of unreleased BBC sessions, including a December 1969 concert recorded for David Symonds, together with many 'work in progress' mixes and alternate final mixes, has resulted in the addition of these recordings as bonus material," he said.
He added: "Over the past decade, many important artists (notably the Beatles, with their 'Anthology' albums and the Who) have realized the value of satisfying their dedicated legions of fans by presenting recordings that show the evolution of classic material either in the form of demos or alternate mixes. With such an important act as the Moody Blues, the fan base is noted for its keen interest in the recording process of their many classic albums. Therefore, after searching Decca and Threshold archives, together with the BBC, notable recordings have been compiled as bonus tracks, including three previously unreleased songs."
Street said that the albums will be remixed by "our own engineer and project consultant, in conjunction with members of the band," but that Clarke and Varnals will not be involved.
