Essential: a masterpiece of Progressive rock music
German band HAZE's 1971 album Hazecolor-Dia is primarily remembered today for possessing an interesting album cover. The cover, which was designed by NINE DAYS' WONDER founder and singer Walter SEYFFER, featured a plastic transparency over a picture of the band to create a slide picture frame. Neat, huh? Copies of the original vinyl are quite expensive these days.
