Emo revival

The emo revival, or fourth wave emo,^[2] was an underground emo movement which began in the late 2000s and flourished until the mid-to-late 2010s. The movement began towards the end of the 2000s third-wave emo, with Pennsylvania-based groups such as Tigers Jaw, Algernon Cadwallader and Snowing eschewing that era's mainstream sensibilities in favor of influence from 1990s Midwest emo (i.e., second wave emo). Acts like Touché Amoré, La Dispute and Defeater drew from 1990s emo and especially its heavier counterparts, such as screamo and post-hardcore.

The movement had become prominent in underground music by the mid-2010s, with influential releases from era-defining groups like Modern Baseball, the Hotelier and Joyce Manor. It also expanded in scope and sonic diversity during this period. Soft grunge was pioneered by such groups as Title Fight, Basement, Citizen and Turnover, while State Faults, Birds in Row and Portrayal of Guilt pushed the boundaries of screamo. Fourth-wave emo entered a decline toward the decade's end, as influential bands disbanded or entered periods of hiatus. A fifth-wave of bands began pushing the genre into more experimental territory, often embracing post-rock; examples include Pool Kids, Glass Beach and Awakebutstillinbed.
