1957 and 1958 marked a true turning point in the career of Herbie Mann as he began to abandon the straight-edge cool jazz style for which he had become best known, and increasingly take influence from outside his traditional fare. This collection, featuring eight original Herbie Mann albums, all now in fully remastered format and providing over five hours of music across four CDs, documents perfectly the beginnings of this master musicians most transitional and challenging period, as it highlights the great man''s ability to adopt increasingly experimental forms in a surprisingly subtle manner.
