After releasing the groundbreaking 'Talking Book,' Wonder went on to release, in 1973, what is considered by many to be his magnum opus. Here Wonder brings social commentary to the fore with classic hits like 'Higher Ground' and 'Living For The City' and his commentary on American urban living has remained some of the most poignant in music history. The album also won three Grammys, including album of the year. Comes in a gatefold sleeve.
