A few years ago the Samurai champloo soundtrack changed my life, and I started more and more to listen to instrumental hip hop more and more. Now I'm at the point where I almost cannot stand songs with lyrics besides folk music from Terry Callier
Right now I'm working my way through the Ta-ku discog, Slum village, Jazz liberatorz and Grammatik. I was sort of leery of Ta-ku a few years back but he's gotten so good now that he's broken away from borrowing styles from others. 'Do what you love' is so breathtaking!
My playlistings are
Jdilla's: Illa Jay, Vintage along with replaying the purple single until I can't anymore.
Fat Jon's Entire discography that I can find
Michita: Dawning and a full life
Blazo: Colors of jazz (that summertime remix is one of my favorites)
