Innovation and Diversity Redux: Analyzing Musical Form and Content in the American Recording Industry, 1990-2009.

Using the American recording industry as a case study, this article analyzes innovation and diversity concurrently and outlines the analytical purchase gained from doing so; examines the effects of performer incumbency and combinatorial role patterns, thereby offering an empirical application of the "role as resource" perspective (Baker and Faulkner 1991); and provides data on an underexplored era in which the emergence o f digital technology has had wide-ranging repercussions. Regressing measures of innovation (form) and diversity (content) on incumbency status and combinatorial role patterns reveals that innovation and diversity operate through distinct collaborative patterns. New artists are found to be carriers of musical innovation, and while performing artists with autonomy over the roles of songwriter and producer are more likely to be progenitors of musical diversity, innovation emerges from role specialization. Artistic roles and performer attributes, moreover, come together in particular ways to influence diversity and innovation depending on the environmental context. Post compact disc (CD) format era, innovation wrought by producer specialization is predominant, but the music is devoid of diversity. I conclude by arguing that the manner in which configurations o f diversity and innovation interact has implications both for cultural production and reception. [ABSTRACT FROM AUTHOR]
