My Morning Jacket - the day is coming, 2011

"The album cover is a close-up shot of a Magic eye tube fitted onto vintage radio receivers from the 1930s. The purpose of tuning eyes in these radio sets was to help tune a station in at its strongest point on the dial. So when the perfect frequency was found, the Magic Tuning Eye would be lit up all the way (like the album cover's). The percentage of light shown signified the strength of the signal."
