Eduardo Navas, author of Remix Theory (Springer, 2012), asked me to write an essay for The Routledge Companion to Remix Studies (Routledge, 2014) collection, co-edited by Navas, Owen Gallagher, and xtine burrough. They describe my chapter (“The End of an Aura: Nostalgia, Memory, and the Haunting of Hip-hop”) like this: “Christopher’s text by and large comprises a series of quotes by divergent authors, ranging from cyberpunk to hip-hop, which take the shape of an intertextual collage that turns into a case study of authenticity in the time of constant digital reproduction.” I was more than glad to have a venue in which to expand a few pieces that had originally appeared on this site combining sampling, mediated memories, Walter Benjamin, and cyberpunk.
