He was raised by his mother, Karesse Grenier, a New York City real estate agent. Growing up, he didn't know who his father was. His parents met while living in a commune, and split up soon after Adrian's birth. The documentary Shot in the Dark (2002) covers Adrian's search to find out who his father was, meet and get to know him. Also involved in the film, as both producer and on-camera interviewer, was Adrian's friend Jonathan Davidson.
