As is well known, out of Chicago’s first ten albums, only Chicago IV, a 4 LP set recorded at The Carnegie Hall, was never released in quad, even though it was planned to be. The main reason for it’s cancellation was probably down to sound quality, which was primarily down to the poor acoustics in the hall.
During testing of an improved version of the Ambisonic SuperStereo process, i used two albums, one being a nice baroque album supplied by Owen Smith, and the other was Chicago IV. The results have moved me to break one of my own rules.
As this blog is dedicated to the decoding of quadraphonic & surround encoded material, this is a one off release.
I hope you all enjoy it in the way it is meant: to complete the ten album series in quad.
