David Jeffers has always understood the world through sound. As a kid, he bounced beats between tape decks and built speaker boxes from spare parts. After college, he founded an underground hip hop label. Then came the day that split his life in two. And in the quiet that followed, David started listening more deeply… and piece by piece, he built a new life, guided not by what he lost, but what he could create.
