His death was announced Monday in a post on his Instagram account, sparking an outpouring of tributes from the music community. Ka was praised for his reflective lyrics, minimalist production, and dedication to both his craft and the city he served.
“Ka lived a life of service — to his city, to his community, and to his music,” the Instagram statement read. “He leaves behind an extraordinary legacy as a recording artist.”
A native of Brownsville, Ka spent 20 years with the New York Fire Department, rising to the rank of captain. He also worked as a first responder during the Sept. 11 attacks, a role he rarely discussed publicly but one that deeply influenced his worldview and music.
Known for his introspective, poetic style, Ka’s music was often described as a form of “quiet rage,” characterized by its understated delivery and deeply introspective lyrics that explored themes of survival, struggle, and social justice, drawing on his experiences both in the streets and in the firehouse. On his critically acclaimed 2016 album "Honor Killed the Samurai," Ka rapped: "With bars of greed, I plead, how many cars you need? / When fathers bleed to fill ribs of kids that hardly read."
Though Ka had been rapping since the early 1990s, it wasn’t until the release of "Iron Works" in 2008 that he gained recognition in the underground hip-hop scene. In an interview with Complex, Ka said the album was a personal milestone, a way to show his mother that his years spent pursuing music hadn’t been in vain. “I wanted to give my mother a CD to put in her hand,” he said.
His lyrical mastery and minimalist production earned Ka a devoted following and widespread respect in the hip-hop world. He was fiercely independent, releasing all of his albums on his own label and maintaining creative control over his music. The Fader once called him “New York rap’s greatest living treasure,” while journalist Jeff Weiss described him as “the master of quiet rage,” noting that Ka’s music carried “pain, grief, and wisdom in every bar.”
Ka collaborated with prominent artists such as Wu-Tang Clan’s GZA and producer Roc Marciano, continuing to push the boundaries of hip-hop with each release. His most recent project, "The Thief Next to Jesus," was released in August 2024.
Ka is survived by his wife, Mimi Valdes, who paid tribute to him on Instagram, calling him "my king, my hero, my best friend." He is also survived by his mother and sister.
