From Gavin: “The album is a definitive collection of my fan fiction and horror tribute songs, newly remixed and remastered, topped off with 3 unreleased tracks for 2025 (one about Quint from Jaws, one about neighborly werewolves, and one from the perspective of a robot house with poor sportsmanship).”

I recently had the pleasure of mastering the new album “Live at The Blue Door” by aka The Queen of Oklahoma.
Good stuff! Thanks for having me involved, Carter!

For the last 20 years, this Oklahoman has consistently delivered high-quality songwriting and gorgeous vocals, proving that she is one of the very best around. Her previous albums were produced in a studio setting using a full band, while her latest release captures a live solo performance. “I play a lot of solo shows, as well as with a band. On this album, I wanted a stripped-down recording to highlight the songs and me singing them.” In November 2024, Sampson teamed up with long-time bandmate and engineer Kyle Reid to record two live shows at The Blue Door. The Blue Door has been the premier listening room in OKC and a home base venue for the artist for many years. Live at The Blue Door is Carter Sampson at her best, riding the strength of her songs and her powerful voice.
