5. Sun Kil Moon - April (2008): Sun Kil Moon's second proper LP may not hit the same raw, emotionally bare nerves as its predecessor, but it's a stunning work of art, probably Kozelek's most tonally varied collection to date. Opener "Lost Verses" features a soaring chorus (sung with Ben Gibbard) and a guitar fade-out worthy of Crazy Horse. "Heron Blue" is as spare and bleak as a cemetery blanketed in fog. The album's incredible climax, "Tonight In Bilbao," has instrumental intricacy worthy of Kozelek's heroes Yes. But mentioning highlights is futile -- April is flawless.
