King Crimson 2015 Complete 10 Shows Series Part 3 Release No.1 presents the first night of the Osaka Festival Hall two-day performances from December 12, 2015, released on SHM-CD as a Japan-only original project and issued as a 2-disc set in an E-style gatefold cardboard sleeve, documenting the fifth show of the 10-show Japan tour undertaken by Millennium King Crimson during their second year after resuming activities in 2014, with this final third phase of releases following earlier installments in December 2025 and February and covering the regional dates in Osaka, Takamatsu, and the concluding Nagoya show, as the Osaka opening night followed four consecutive Tokyo warm-up performances and marked the band entering full engine mode, notable for having the highest ratio of classic representative songs across the entire tour and featuring an orthodox setlist that included all major songs except Sailor's Tale, One More Red Nightmare, and VROOOM, while showcasing the enhanced interplay between the three drummers and Tony Levin's bass, particularly in the second half beginning with a jazz-funk reinterpretation of The ConstruKction of Light that introduced a new groove and led into a succession of iconic tracks, with the master sourced from digitally recorded data captured on the day and mixed by Alex Mundy.
