This recent gospel compilation from Swedish producer and collector Per Notini is a three disc, 84 track set focused exclusively on a capella singing without any instrumental accompaniment. Featuring many well-known quartets such as the Fairfield Four and Soul Stirrers as well as lesser known artists, the set traces stylistic changes over a thirty year period, concluding in 1969 before the ‘contemporary’ gospel era. These groups created some of the most inventive and progressive African American vocal music of the post-war period, which had a profound effect on later R&B and soul artists, not to mention artists across all other genres.
