Cover art for Iridium lyrics by Dark Tranquillity

Mikael Stanne:

"I accept the idea that on cosmic level nothing can stay forever. There is an end to everything, nothing's eternal. Even the small particles in the atmosphere will disintegrate and nothing will be left of them. I think it's a perfect ending for the album."
