"It was a political statement to the entire world that he kept this garden going. He was this deeply philosophical character and to him it was an act of defiance to grow flowers in the middle of Aleppo.

When we were looking at that song, we decided that should be the focus geographically" - Edge on Summer of Love, 2017
