The work is devoted to an overview of the culture of music festivals of the modern era, from their beginnings with classical music festivals to electronic music festivals, which nowadays dominate the offer and quantity of festivals. The paper presents the socio-political context of the time in which certain types of music festivals were created and their roles and influences on their transformation over time. The paper presents an analysis of the culture of electronic music festivals in the Republic of Croatia, with an emphasis on theoretical and field research on the development and nurturing of the culture of electronic music festivals on the island of Pag and Krk. The analysis presents the location and content differences of the two islands, then the differences between local and foreign festival productions, and examines the views of festival attendees in the area of Krk, Rijeka and the surrounding area and the problems faced by the local organization of the festival on the island of Krk. Current festivals on the Croatian scene and their positive and negative impacts on society, tourism, location, and individuals (organizers, performers, attendees...) are highlighted in the paper. In accordance with the postmodernist era and the development of youth culture, to which festivals of this type belong, postsubcultural theory and a new form of tourism are presented. This new form of tourism is born as a result of the explosion of electronic music festivals, called clubbing tourism. If the festivals of electronic music dominate the festival summer scene so much and they are increasingly added to the tourist offers of the certain locations, there is a question that runs through this paper – do they stay in the domain of the underground culture, or are that boundaries like in the concept of subculture, being blurred together more so it can be said that they are slowly transitioning in the mainstream
