Books - nonfiction - film books, theory or scandalous stories of
starlets all work great. Hip-hop books do just fine as well.
Crime and Punishment was my favorite book for a long time. Lolita
is it's own category because it kicks so much ass. I have a guilt
complex about not reading enough, so when I read a novel, I pick
some arduous classic as a form of penance.
Movies (general in life) - I'm a ginormous film nerd.
In the artsier realm - anything Chris Marker, Hitchcock, Claire
Denis, Bresson, Godard, Lynch, Mitzoguchi, etc... I also love old
Hollywood and movies where dudes blow shit up good for America or
Music: grew up on hip-hop but will listen to anything. Recently
Archie Shepp, Mixes I've made, Arthur Russell, Lea Bertucci,
Excepter, David Crosby, Run The Jewels, Bardo Pond, D'Angelo, The
Artifacts, Butthole Surfers, Converge.
Shows - The Wire, Seinfeld, Mad Men, Breaking Bad, The Office UK,
Louie, Veep, The Simpsons.
Food - Lots. All.
