Eternity of Dimming is the third full-length studio album by Frontier Ruckus. A double album of 20 songs, the record is nearly an hour and a half in duration. The album's lyrical text is also unusually prolific, containing approximately 5,600 words. Despite the dense and hardly immediate nature of the record, Eternity of Dimming received mostly favorable reviews—eliciting reactions of both hyperbolic praise and occasional vexation. Thematically, the record details childhood and adolescent memory within the suburban landscape of Metro Detroit.
