The Em-related part of the interview is here:
Lately, I’ve been in an almost KRS-One state of mind: everyone is hip-hop. My favorite section in the book is “You Might Be A Rapper”: I really think everyone can access that creative, artfully aggressive sensibility. I’ve been fascinated for a long time with David Foster Wallace. One of his first books to come out was "Signifying Rappers," (he co-wrote it with Mark Costello). It came out before the mid-nineties explosion, and it’s about Public Enemy, A Tribe Called Quest, and De La Soul—all before Biggie and 2Pac and Jay-Z. I think of him as being very similar to Eminem, in the sense that there’s a hyper, caged-in intellectual sensibility that’s estranged, in some way, from the world it’s engaging with; someone who has these flairs of creativity and artistry, but still has a very strong integrity, a respect for formalism and craft. There is a lot of respect and history embedded in their work.
It's not exactly news, or even important, I just thought that was a really eloquent description of Em, and wanted to share.
