Richard Antoine White slept under trees and on friends’ couches with an alcoholic mom when he was a kid. But when foster parents took him in, he found out that he was good at music – and his path has provided a Baltimore documentary duo with a great project. White mentors other kids in need of a hand up, but also, and this is a fun one, he is “particularly passionate about baroque music (he has transcribed works of Bach for the tuba).”
