Bonnie Prince Billy/Bitchin' Bajas/Bill Mackay

Music fans may have heard Will Oldham's music more than they realize, given the nicknames he's worked under throughout his 23-year career writing and performing Americana and — including as Palace Brothers, Palace Music, and, since 1998, Bonnie "Prince" Billy. Oldham's fragile voice is often backed by subtle guitar and piano; the songwriter's real artistry shines through on the deep-cutting lyrics to his songs, such as on "I See a Darkness." (DeSmit)
