Hawthorne Heights is an American rock band from Dayton, Ohio, known for shaping the sound of early 2000s emo and post-hardcore. Formed in 2001, the band first broke into the national spotlight with their 2004 debut album The Silence in Black and White, featuring the anthems “Ohio Is for Lovers” and “Niki FM.” Their blend of emotionally charged lyrics, melodic hooks, and heavy guitars quickly earned them a devoted following and a defining place in the alternative scene.

Letlive. specializes in post-hard-core, art-punk, experimental rock, and metalcore. It is best remembered for its sophomore album, Fake History, and its third album, The Blackest Beautiful.
