"Japanese original reissue of "Super Session" from Mike Bloomfield, Al Kooper, Stephen Stills. To commemorate the 55th anniversary of the release of "Super Session," Quadraphonic (4-channel mix), which first appeared in 1972, has been revived for the first time in the world as an SA-CD multi-hybrid disc after 51 years. The multi-channel SA-CD layer is the latest remastered version using DSD mastering in Japan of the high-resolution files dropped from the original master tapes of the Quadraphonic LP, and the CD layer also uses the SA-CD stereo high-resolution master. Features 7-inch cardboard sleeve packaging, faithfully replicating its Japanese Quadraphonic LP design. 2023 remastering."
This will be the first digital release of the quad mix, as the 2014 AF SACD used Al Kooper's 5.1 remix.
