Movements formed in Rancho Santa Margarita, California, in 2015 and quickly became one of the most recognizable bands in the emo-leaning post-hardcore revival. The group's lineup of Patrick Miranda, Ira George, Austin Cressey, and Spencer York built its identity on tightly wound guitar work, confessional vocals, and lyrics that confront mental health, grief, intimacy, and emotional exhaustion. After signing with Fearless Records following their earliest live activity, Movements released Outgrown Things in 2016, an EP that introduced their blend of spoken-word intensity, melodic post-hardcore, and soft-grunge atmosphere. Their 2017 debut album Feel Something became the defining release of their early career, with "Daylily," "Colorblind," "Full Circle," and "Deadly Dull" turning vulnerability into anthemic, cathartic rock. No Good Left to Give followed in 2020 with a darker, more spacious tone, while RUCKUS! in 2023 pushed the band toward more varied rhythms, sharper hooks, and broader alternative rock textures. Movements remain rooted in emotionally transparent post-hardcore, but their catalog shows a steady move from raw catharsis toward more expansive and unpredictable songwriting.
