Periphery and Warframe 1999 come together with a new guest track, but how on earth did that happen?

Warframe 1999: Techrot Encore is out, and it's a lot of fun. But, one thing you may not have noticed as a player or a far-flung spectator is that progressive metal band Periphery worked alongside Digital Extremes on a special guest track for the update. It all fits within the rock band vibe that came with Temple and the new defence mission.
