You have to wonder when Mark Kozelek will give himself a break. If you were to judge the totality of his life by his music, it would make for a pretty bleak story. As the driving creative force behind the Red House Painters and, more recently, Sun Kil Moon, Kozelek, 47, is the definition of a mope rock troubadour. For more than 25 years, he’s been crafting sweetly despondent odes to heartache, letting the light creep in only for the briefest of moments. That’s a long time to wallow in the muck, but Kozelek has always done his best work under the threat of an impending storm. When life gives him lemons, he squeezes them with a vice grip for every last drop of acidic juice.
