The interview analyses the genesis of Roger Keil’s works on Los Angeles (L.A.). We discuss the writings that influenced him when doing research in L.A. for his PhD dissertation notably Mike Davis’s writings on L.A. but also French theorists such as Jean Baudrillard and Henri Lefebvre’s works on the representation of space and the postmodern geographers led by Edward Soja. My aim was to understand the value of city representations for urban theory. Popular music as a media being the focus of this collection, we discuss the connection between music and place. Roger Keil makes the point with the example of hip-hop band NWA and Compton that musicians also produce space and can reveal a place to the world. The chapter discusses the historical trajectory of urban theory on L.A. by reflecting on the 1980s L.A. School and on the more recent theories developed by urban scholars at UCLA. Today’s limitless representations of the city through new media now available in our hands were also part of the discussion. Roger Keil’s deep knowledge and understanding of Los Angeles shed light on the connection between the city’s urban infrastructures and the local underground music scene in the 1980s and 1990s with mentions of innovative music coming from the suburbs.
