Okay, Line Out smarties, I once again need your help.
I listen to music when I write. This music must be close to word-free, and maintain a steady-ish sound/vibe.
Previous champions of the writing music genre that I have subsequently played into the ground and back: Gas' Pop, My Bloody Valentine's Loveless, The Essential Fripp & Eno, assorted Boards of Canada, assorted Steve Reich, J. Dilla's Donuts, Four Tet's Rounds.
(Records that you think might fit the bill but don't: Burial (too jumpy and attention-grabbing in its jumpiness), various beloved African records (just because the words aren't in English doesn't mean they're not distracting), Tom Ze (both previous reasons apply).)
But really: Pop, Loveless, and Steve Reich's Music for 18 Musicians are the pinnacles of the genre as I know it so far, and I NEED MORE.
