I also really liked the Aretha album, was it only dismissed by some of the potential buyers because it had been available on reel?
I think most members on this forum who were really into Quadraphonic audio back in the day would prefer if the labels focused less on reissuing those albums that were available on reel and focus more on those albums that were not released on reel.
As for me, that doesn't matter at all. I'm just looking for those releases that have both the best music and the best Quadraphonic mix to be put out there again.
