The inside of my head is an absolute crap place for productivity. I tend to fixate on old horrors, recent regrets and small shames that swirl around the inside of my brain like greasy water bound down a drain. It makes for a lot of noise while I'm trying to write or focus on my day job--listening to music with lyrics or, on bad days, even a melody, can lead me to distraction. When I'm set up in a coffee shop or another noisy locale and need to churn out some words, I wind up getting nowhere.
Last year, a friend turned me on to Lustmord: it's the working name of Welsh musician, sound engineer and, as near as I can tell, dark wizard, Brian Williams. Wikipedia notes that Williams is often credited with inventing Dark Ambient Music. I credit him with giving me the space I need in my skull to get work done.
In turns, Lustmord's music has overwhelmed me with feelings of calm, dread and and well-being. Played late in the evening in concert with medicinal amounts of Jameson, it helps to distract me from the pain in my body and the dogs barking in my head.
