By combing the most extreme corners of heavy music and emo, Capstan sharpen, strain, and strengthen a slick signature style of progressive post-hardcore. The Florida quintet—Anthony DeMario [vocals], Harrison Bormann [guitar], Andrew “Bozz” Bozymowski [bass, vocals], Joseph Mabry [guitar], and Scott Fisher [drums]—vault from moments of masterful melody into claustrophobic cacophony seamlessly on their 2019 full-length debut, Restless Heart, Keep Running [Fearless Records].
