On the seminal songwriter, who died four years ago today, in his final days before succumbing to dipsomania.

A profile of singer-songwriter Will Oldham.

He has settled into character as an uncanny troubadour, singing a sort of transfigured country music, and he has become, in his own subterranean way, a canonical figure. Johnny Cash covered him, Björk has championed him (she invited him to appear on the soundtrack of “Drawing Restraint 9”), and Madonna, he suspects, has quoted him (her song “Let It Will Be” seems to borrow from his “O Let It Be,” though he says, “I’m fully prepared to accept that it’s a coincidence”).
