The world first heard Mark Kozelek's creaking baritone in 1992 fronting Red House Painters, swathed in the downbeat rhythms and guitars of the sadcore sound. But with Sun Kil Moon, the Ohio-born songwriter proved that his autobiographical stream of consciousness—ruminating on concerts he's seen, the tragic lives of boxers or countless kith and kin—is cathartically devastating whether accompanied by a band, as he often still is, or just his guitar. At the heart of it all, including his drastic Modest Mouse and AC/DC remakes, is a deep sentimentality and a wry chuckle for life's heaviness.
