21C Media Group

New York, New York, United States

Publicity, digital strategy, and branding for music, culture, and the performing arts

21C Media Group works exclusively within music, culture, and the performing arts, handling publicity, digital media, and consulting for a roster that spans nonprofits and Fortune 500 companies. The agency's focus sits squarely on organizations and artists whose work depends on public visibility and institutional credibility, from orchestras to cultural diplomacy initiatives.

Services cover public relations and media advocacy, digital strategy and social media, imaging and branding, editorial and media production, organizational strategy and consulting, and special events and projects. This range lets the agency move between career-building publicity for individual artists and institutional strategy for larger cultural organizations, often folding branding, digital presence, and event planning into a single engagement rather than treating them as separate tracks.

Work with the Afghanistan National Institute of Music illustrates this breadth, combining branding, consulting, digital diplomacy, events, PR, and production under one client relationship. Other projects include Yo-Yo Ma's #SongsOfComfort initiative and the London Symphony Orchestra's U.S. tour in 2025, both examples of the agency applying its performing-arts focus to high-visibility cultural moments that require coordinated media and digital handling.
