This thesis deals with the topic of sociological understanding of the phenomenon of subculture, as a society within society. An overview of the history of theoretical and empirical development of the sociology of subcultures, briefly presents the most influential contributions of the Chicago School, the theory of delinquent subculture, symbolic interactionism, the Birmingham School and post-subcultural studies. Also, the concept of moral panic, labeling theory and the role of the mass media in the construction of the subculture are discussed. The main goal of the paper is to describe, analyze and understand the characteristics of the subcultural capital of Zagreb heavy metal scene and bring the characteristics of S. Thornton's concept of subcultural capital in relation to P. Bourdieu's concept of social capital, whose work Thornton was inspired by. The ultimate goal is to analyze the impact of these two concepts on the formation of the identity of members of Zagreb heavy metal scene and their choice of lifestyle. The sample consists of relevant members of the Zagreb heavy metal scene, who are active participants of the scene. The research is based on a qualitative methodology. The method used is a semistructured interview and the research instrument is an interview protocol. The collected data were processed using Nvivo software for quality data analysis. The research includes findings on a kind of generational conflict on Zagreb heavy metal scene, with older participants showing the characteristics of traditional heavy metal subculture, while younger participants show the characteristics of culture described in the works of post-subcultural studies. The paper raises the question of whether the heavy metal subculture in Zagreb came to an end, or whether this subculture became mainstream culture, like the club culture recognized in S. Thornton's works.
