check your local Vinyl record shop to find this treasure
The best way to tell if a pressing features the East Coast Mix is to check the record matrices: affected copies feature the letter W or X in the matrix number (i.e. ST1-2442-W4P), signifying the New York plant.
It may be possible to differentiate by checking the cover: the “New Improved Full Dimensional Stereo” logo at the top of the cover appears in black text against a white background in the East Coast Mix, above the photo which is therefore shortened, as opposed to appearing in brown/orange text against the dark brown background of the cover photo.
