This article examines the concept of the term underground and its association with a range of dance music parties and venues that emerged in Liverpool, UK between 2008 and 2023. Drawing on a critical review of literature relating to the term, underground is positioned as a cultural signifier exhibiting three core characteristics: (1) as secretive resistance; (2) as a countercultural antithesis to mainstream; and (3) as a social imaginary. Using ethnographic material from scene practitioner interviews (n = 35) and an online survey of clubbers (n = 194), the article analyses discourses towards the underground as a concept, and how underground characteristics influence scene cultural practices. The findings reveal participants’ use of the term as a descriptor of experiential feelings within temporal spaces. Drawing on the work of Gopaldas, these feelings as situated as sentiments which inform the shared intentions and practices within a local dance music scene.
