Hmmm..., The Analogue Production Blue Notes have not yet been released. But both the AP and the Music Matters Blue Notes are/will be mastered by Steve Hoffman and Kevin Gray on the same equipment, and both are/will be pressed in the same pressing plant, RTI. They should be identical in their sonics, the difference will be in the packaging.
From what I hear comparing the Fantasy 45 series from Analogue Productions and the first of the two Blue Notes from Music Matters, I don't expect to hear any sonic differences between the Blue Notes from Analogue Productions and the Blue Notes from Music Matters.
