Imagine Dragons wrote the song after an early screening of Transformers: Age of Extinction. The song has been implemented in key parts of the film by director Michael Bay.

Imagine Dragons will perform the song live at the Hong Kong premiere of Transformers: Age of Extinction on June 19. Imagine Dragons are the Grammy Award-winning alternative rock band whose hit single, "Radioactive," helped to propel their debut album, Night Visions, to platinum sales status. Transformers: Age of Extinction comes to theaters June 27.
