There was also often an emphasis on black nationalism. Hip hop scholar Michael Eric Dyson stated, "during the golden age of hip hop, from 1987 to 1993, Afrocentric and black nationalist rap were prominent", and critic Scott Thill described the time as "the golden age of hip hop, the late '80s and early '90s when the form most capably fused the militancy of its Black Panther and Watts Prophets forebears with the wide-open cultural experimentalism of De La Soul and others". Stylistic variety was also prominent; MSNBC said that in the golden age, "rappers had an individual sound that was dictated by their region and their communities, not by a marketing strategist," the "Village Voice" referred to the golden age's "eclecticism", and Ben Duinker and Denis Martin of "Empirical Musicology Review" wrote that "The constant flow of new, boundary-pushing Golden Age album releases exemplifies this era's unprecedented stylistic fluidity."
