Mainstream jazz is a term coined in 1954 by the critic Stanley Dance; whilst it lacks a uniform definition in jazz scholarship, it refers to the swing-oriented style of musicians such as Buck Clayton, who deliberately distanced themselves from the modernisation brought about by bebop. Since then, it has come to denote more accessible, melody-driven forms of jazz that lie between traditional and modern jazz. From the 1970s onwards, it experienced a revival through the Concord Jazz label, featuring artists such as Scott Hamilton, amongst others.
