Trap is a relatively new musical genre that is being listened to by an increasing number of young people in Croatia. This is evidenced by the large turnout of young people at trap concerts and festivals, as well as the large audience of trap on streaming platforms such as Spotify and Deezer. Trap developed in the south of the USA and is a subgenre of hip hop music. In Croatia, we associate the beginning of the development of trap music with the early 2010s, and the first well-known performers are: "Kiša metaka", "High5" and "Kukus". In this work, the researcher analyzes and discusses trap in Zagreb by means of insider ethnography and the use of participatory observation methods, semi-structured interviews and reflective thematic analysis. In the first part of the paper, the researcher defines trap music and considers the relevance of this topic, in the second part of the paper, the key subcultural and post-subcultural theoretical concepts and the research implementation methodology are stated. In the central part of the paper, the results of the conducted research are presented, while in the Discussion and Conclusion chapters relevant theoretical concepts are connected with the research results, and the researcher answers the research question based on the applicability of post-subcultural concepts to trap in Zagreb. The key concepts of subculturalism such as class, resistance proved to be insufficiently relevant. The research has shown the applicability of the post-subcultural concepts of "neo tribe", "lifestyle" and "scene" to the trepers, however, certain classic subcultural characteristics such as bricolage are also not negligible.
