Rebecca Rechtszaid took 13 years of vocal lessons, played in South Florida garage bands, and briefly planned on being a rock star. Then she went to Harvard Law instead, ran the student clinic that gives free contract review to musicians who can’t afford lawyers, spent five years inside one of the four American performing rights organizations, led legal for creator programs at Meta, and left to open her own firm. Her first clients, before law school and before she was licensed to do any of it, were her younger sister’s brand deals.
