VINYL. The Headquarters Sessions is an 84-track 3-CD set by the Monkees containing 60 previously unreleased recordings from the sessions that produced the band's third album, Headquarters.
It includes recordings from sessions where the band exercised creative control over all aspects of the recording process and where they played most of the instruments. All vocal masters from the sessions that were not included on the original stereo album are included as well as the surviving vocal demos and a few tracks with vocals which were never completed. In addition, the original mono masters are presented in an initially proposed, but ultimately unused, running order.
