QuadraphonicQuad's Label Checklists and Quadraphonic Histories of American Records Companies
This information was compiled using information from fellow quad collectors and the various printed publications from the 1970's, but mostly from Larry Clifton's "Quad Incorporated" publication, which cataloged all quadraphonic recordings available at the time. It is through Larry's incredible effort that these checklists could be compiled with some authority.
NOTE: Not all of the below label listings are completed at this time
