Sparks was born and raised largely in the Dorchester neighborhood of Boston. His parents got divorced when he was around 4 years old, and he lived with his mother for most of his childhood. He began using his mother's stereo as a turntable at age 10 and began manipulating his favorite parts of recordings to create new songs. When he was 12, he stole his first set of actual turntables and started making music for his groups and local artists. Sparks was a rapper and a dancer who, with his entourage, would win local talent shows.
