Children, particularly girls, spend hours every day fetching water. These are hours that could be spent in school. Every 20 seconds a child dies from drinking unsafe water." Yeah Yeah Yeahs went on hiatus in 2014 after finishing the tour behind their fourth album, Mosquito. In 2015, Karen O told Rolling Stone she was "in the full-time job of [motherhood] at the moment," focusing more on her personal life than music. "It's just waiting to see how everything works out with starting a family and seizing the moment when it strikes," she said.
