RK/music

What RK/music does

RK/music, doing business as Mixology Post, is a New York-based, full-service music and audio-post production agency founded in 1979. The firm serves enterprise brands with a portfolio of interconnected audio services spanning original music composition, voice-over recording and mixing (including theatrical surround mix), licensed music procurement with rights negotiation, sound design, audio branding, custom music, and audio rescue/cleanup. Client work spans entertainment and television (HBO, American Horror Story, AMC), sports streaming (DAZN), documentary (National Geographic Sharkfest), athletic apparel (Nike), beverage (Evian), convenience retail (7-Eleven), fashion/automotive (Diesel), and advocacy (NRDC Action Fund), demonstrating a horizontal cross-vertical brand orientation rather than a sector-specialist model.

The underlying technology stack is fundamentally creative-services based rather than software-platform based: composition, mixing, sound design, and licensing are executed by an eight-person in-house team using standard professional audio production workflows, proprietary sound libraries, and external relationships with music publishers, libraries, and labels for licensing. There is no disclosed proprietary software platform, API, or technology product; the firm's IP resides in its creative output, brand relationships, and counterparty relationships rather than in code or data assets.

The business model is professional services with a licensing-royalties complement. Revenue is generated via quote-based project engagements acquired through direct enterprise sales, supported by a portfolio-led website that functions as the primary inbound marketing channel showcasing named brand work as social proof. Distribution is global in principle via direct client engagement, but operations are centered at a single New York headquarters. Pricing is not publicly disclosed and is presumably negotiated per project, consistent with custom creative-services engagements of this nature.
