Hip-hoppers in Istanbul, Turkey, spend much discursive energy talking and rapping about how the Turkish hip-hop movement is underground, putting a particularly local spin on their uses of a global cultural form. This spatial metaphor has thus become central to local constructions of hip-hop in Istanbul. This paper explores the different meanings the underground concept has for Turkish hip-hoppers through a combination of ethnographic research and readings of locally produced hip-hop texts. Through discourses on and around the underground metaphor, Turkish hip-hoppers use the globally circulating music genre of rap and the associated arts of hip-hop to construct a specifically local identity, re-emplacing rap and hip-hop within the landscape of Istanbul. The paper uses this case study to explore how people can use mediated music in constructing new imaginaries and identities and more specifically how people can use mediated music as a vehicle for the imagining of place.
