When founded in 2005, when the average member's age was 16, Marionette quickly made a name for themselves in the Swedish metal scene by winning and placing high in many national and international music contests.
In support of the EP, Terror Hearts – which was mixed and mastered by Fredrick Nordström (In Flames, At the Gates) – Marionette shared the stage with some of the world's most renowned metal acts including: Machine Head, Slayer, Mastodon, Meshuggah, and Candlemass among others.
In keeping with the approach established for Spite, Marionette assembled a production team for Enemies which included Pontus Hjelm (Dead by April) and two-time Swedish Grammy award-winning producer Åke Parmerud.
Fredrik Nordström (In Flames, At the Gates, Bring Me the Horizon) and Peter in De Betou (Dimmu Borgir, Meshuggah) handled mixing and mastering duties respectively.
Special recognition was given to the band's aggressive sound, "stylistic depth", "technical cohesion", and an intrinsic ability to walk the line between relentless heaviness and commercial appeal.
