Breaking Rust, an AI "band" that appeared on the internet in the middle of October based on its presence on Instagram, topped the chart last week with a song called Walk My Walk. Look at Breaking Rust's social media pages and you'll find nothing to indicate there's an actual human involved in the music-making portion of the band's songs - just a chiseled-jawed, clearly AI-generated cowboy, and video clips featuring folksy people doing folksy things or slow-walking away from the camera.
