Citizen is an American rock band that emerged from the Southeast Michigan and Northwest Ohio music scene in 2009. Comprising Mat Kerekes (vocals), Nick Hamm (lead guitar), Eric Hamm (bass), Mason Mercer (rhythm guitar), and Ben Russin (drums), the band has been signed to Run for Cover Records throughout their career.

Known for their emotionally charged lyrics and evolving sound, Citizen initially displayed a melodic hardcore style. However, they have continuously experimented and incorporated elements of pop punk, post-hardcore, shoegaze, and post-punk into their music, pushing the boundaries of the emo genre. This willingness to evolve has garnered them critical acclaim and a devoted fanbase who appreciate their emotional depth and musical exploration.

Over the course of five studio albums, Citizen has tackled themes of isolation, disillusionment, and the struggle to find meaning in a chaotic world. Their willingness to address these complex emotions with raw honesty has resonated deeply with listeners, making their music a source of comfort and catharsis for many. As they continue to grow and experiment, Citizen remains a compelling force in the alternative music scene, proving that emo can be both introspective and innovative.
