It slipped out of a Mississippi of hot biscuits, genteel table manners and working-class sense, suddenly overturned by a grave sinning and suicide. Carried on an evening breeze of strings and a supple, foreboding voice like sensually charged breath, “Ode to Bilie Joe”—Bobbie Gentry’s 1967 debut as a singer-songwriter and a Number One single for three weeks in the late Summer of Love—was the most psychedelic record of that year not from San Francisco or London, as if Bob Dylan, Neil Young and Brian Wilson had conspired to make a country-rock Pet Sounds. Except Gentry, just 23 when she wrote the song, got there first, in miniature.
