I heard the fear in the first music I ever knew, the music that pumped from boom boxes full of grand boast and bluster. The boys who stood out on Garrison and Liberty up on Park Heights loved this music because it told them, against all evidence and odds, that they were masters of their own lives, their own streets, and their own bodies. I saw it in the girls, in their loud laughter, in their gilded bamboo earrings that announced their names thrice over.

How the earrings can announce someone's name? Is there such an expression?
