Matthew McConaughey performed the song “Quill” for the upcoming motion picture “The Rivals of Amziah King” [1, 2].

The release highlights the actor's musical abilities as part of a broader promotional campaign for the film, which blends drama with specific industry themes.

Lakeshore Records released the track as a single and music video this Friday [1, 2]. The song is part of the original motion-picture soundtrack and features McConaughey on both vocals and the banjo [1, 2].

The film's promotional cycle began earlier this year when the first trailer debuted on Monday, May 11, 2026 [2, 3]. That trailer received a 97% rating on Rotten Tomatoes [4].

Descriptions of the film vary across reports. Some sources describe the project as a beekeeping thriller [5], while others state McConaughey portrays a honey industry tycoon who is also a bluegrass musician [3].

“The Rivals of Amziah King” first premiered last year at the South by Southwest Film Festival 2025 [5]. The movie is scheduled for a wider release in August 2026 [5].

McConaughey performed the track “Quill,” which was released as a single and music video by Lakeshore Records.

The integration of a standalone music video and single suggests the studio is leveraging McConaughey's personal brand and musical skills to create multi-platform interest in the film. By bridging the gap between a festival premiere in 2025 and a general release in 2026, the production is using the soundtrack to maintain momentum for a niche premise involving the honey industry.
