Cold Hart is the moniker of Filipino-American producer, songwriter, and vocalist Jerick Quilisadio, co-founder of the influential emo-rap collective GothBoiClique. Like other members of the crew, Quilisadio combines atmospheric, trap-influenced beats and hazy guitar riffs influenced by emo, darkwave, and pop-punk with lyrics about depression, drugs, and heartbreak. Quilisadio is one of the most prolific members of the group, both as a producer or guest artist on releases by associates like Wicca Phase Springs Eternal and Lil Peep, and as a solo artist. Since the early 2010s, he's released dozens of instrumental beat tapes under his production alias Jayyeah, and countless albums, mixtapes, EPs, and singles as Cold Hart. In 2021, he signed with punk mainstay Epitaph Records and released the full-length Every Day Is a Day.
