The aim of The 21st Century Guide To King Crimson is to replace the Frame By Frame 4-CD compilation (1991), taking advantage of technological advances, ten years of additional live and studio Crimsonising, and twelve years of archiving live material. Frame By Frame"s 3 studio + 1 live albums are being replaced by this two-volume 8-CD Guide, a comprehensive overview for new ears of all that is necessary in the Crimson corpus. Old-generation completists might disagree with some choices, but material not included in the Guide is available for new-generation completists, should they wish. The Guide can only exist now that the complete King Crimson recorded work (live and studio) is, for the first time, in one place: DGM; and a place where, arguably also for the first time, it is not being driven to serve the interests of business."
