I just picked up this up and I am absolutely floored. I was too young to really know what quad was all about and if this SACD is any indication, I may now understand why some of you quadheads fell in love with it. Not only do these songs sound crystal clear, the quad mix is really interesting and not at all murky or distracting. This is going to become a demo disc I believe.....
It's the original '70s Quad Mix from the Analog Master Tapes.
Others in the same catagory (Original Quad Mix --> 5.1 SACD) include the SACDs of Ship Ahoy by the O' Jays and Mike Oldfield's Tubular Bells.
I'd strongly recommend those two as well !
