Perfect Amber is a retracked/remixed version of Amber Grey and Orphan. Featuring additional guitar tracks by Takafumi Matsubara and bass by Mauro Cordoba, Perfect Amber presents an entirely different feel to the original GridLink albums, previously impossible, given the limitations of the original 16-track recordings. Now in line with Matsubara's vision, Perfect Amber represents the intended sound and state of these two albums.
