Eels' alt-rock radio hits earned Mark Oliver Everett a reputation for sardonic sing-alongs. But his deceptively playful songcraft is fuelled by genuine sorrow: 1998's “Elizabeth on the Bathroom Floor” is an orchestral folk lullaby about his sister's suicide, chillingly sung from her perspective. And on 2010's “A Line in the Dirt,” Everett uses a pretty piano-ballad backdrop to frame an unsettling scene of domestic unrest.
