“One thing we saw very early on in the recording process was the fact that this couldn’t be one record,” Imagine Dragons frontman Dan Reynolds tells Apple Music. “There were two different directions, two stories being told, and two timelines. We had songs that I wrote right after my best friend took his life and right after my sister passed away—you know, grieving songs. And then we had songs that were written, because of COVID, almost three years later, when I was in a totally different place. I had a different story to tell.” The band decided to release two variations on a single theme: Mercury - Act 1 addresses the death and grieving process, while Act 2 unpacks the complicated task of trying to move forward."
