Born Laurel Anne Chartow, the artist began her career in the electronic music scene, eventually gaining prominence with her debut studio album Quarantine, released on the Hyperdub label. The record was widely noted for its unconventional vocal processing and atmospheric production, earning the title of album of the year from The Wire.

Her work frequently explores the intersection of ambient textures, jazz-inflected rhythms, and electronic synthesis. She has maintained a prolific output of studio albums and collaborative projects, often incorporating modular synthesis and experimental sound design into her compositions.

Currently based in Los Angeles, Halo continues to be an active figure in the contemporary music landscape. Her recent engagements include a featured performance in the 2026 Off the 405 concert series hosted by the Getty Center.
