Singer Dave Grohl said he wrote the song for his daughter Harper.
The Foo Fighters dropped the third preview of their upcoming 10th studio album Medicine at Midnight on Thursday (Jan. 14), the emotional give peace a chance anthem "Waiting on a War." They then followed up with an official video on Tuesday (Jan. 19).
The mostly-acoustic song was inspired by a disheartening conversation singer Dave Grohl had with his daughter Harper last fall that reminded him of his own fears of nuclear annihilation when he was her age.
"Last fall, as I was driving my daughter to school, she turned to me and asked, 'Daddy, is there going to be a war?,'" Grohl said in a statement. "My heart sank as I realized that she was now living under the same dark cloud that I had felt 40 years ago. I wrote 'Waiting on a War' that day. Everyday waiting for the sky to fall. Is there more to this than that? Is there more to this than just waiting on a war? Because I need more. We all do."
