Mitchell Tenpenny has released “Speed of Light,” a new single and music video that also serves as the title of his 2026 headline tour. Written alongside Teddy Swims, Jesse Hampton, and Dallas Wilson, the song grew out of a session built around euphoric, outer-space feeling music, and it lands exactly there. Tenpenny has been open about the personal weight behind it: with Swims already having cut his own vocal version, Tenpenny went back in and made it his own, describing it as the love song missing from his catalog. The official video, directed by Justin Key and produced by Taillight’s Matt Houser and Nick Lantz, was filmed just outside Nashville in Gallatin, Tennessee, and matches the song’s wide-open feeling frame for frame.
