Background: Najm was born and raised in Tallahassee, Florida. His stage name is short for "Tallahassee Pain", and was chosen because of the hardships he experienced while living there. Najm was brought up in a Muslim household, but he has expressed his lack of interest in the concept of religion. At just three years old he got his first taste of the music business when a friend of the family, gospel jazz artist/producer Ben Tankard, allowed him to spend time and "twist the knobs" at his recording studio.
