His multi-faceted career redefined what it meant to be a modern spoken-word artist. By refusing to separate his identity as a Black man from the characters he brought to life, he established a new standard for authentic storytelling. Whether performing under the moniker muMs da Schemer or delivering unforgettable dialogue in a Hollywood film, Grant remained fiercely dedicated to his craft.
Early Life, Parents, and Education
Family Background and Upbringing in the Bronx
Born on December 18, 1968, in the Bronx, New York City, Craig O’Neil Grant grew up in a supportive and hardworking household. His father, Samuel Grant, earned a living as a carpenter and locksmith at Montefiore Hospital, while his mother, Theresa Grant, worked as an educator. He grew up alongside his brother, Winston Maxwell, in an environment that valued education and discipline.
The foundational stability of his household contrasted sharply with the vibrant, chaotic energy of the Bronx during the 1970s and 1980s. This juxtaposition provided rich thematic material for his later poetry and playwriting. He learned early on how to observe human behavior closely, a skill that later fueled his incredible depth as a character actor.

Overcoming Shyness Through Hip-Hop and Poetry
As a student at Mount St. Michael Academy in the Bronx, Grant battled severe shyness. To cope with his introverted nature and a mild childhood lisp, he turned to the arts.

Poetry became his primary therapeutic outlet, allowing him to articulate complex internal emotions that everyday conversation failed to capture. Around the age of 20, fellow artists nicknamed him Mumbles due to his deliberate speech patterns.
Origin of the Stage Name muMs
Nicknames often stick in artistic circles, but Grant transformed his moniker into a personal philosophy. He shortened Mumbles to muMs and later endowed it with a striking acronymic definition: manipulator under Manipulation. This title reflected his awareness of systemic pressures and his determination to control his own narrative through language and performance.
