I'm not sure what a "Duke Special" is (sounds like a "reverse cowboy" mixed with a "wet sambo"), but The Duke made history recently by performing for the first direct-to-vinyl live recording in an estimated 30 years. I couldn't find specifics on how they recorded 'direct to vinyl', as usually a lacquer, ceramic, plastic, or metal mastering disc is usually the intermediate between live and vinyl. But, anyhow, it's probably the truest recording made in decades, avoiding digital degradation or tape hiss; if only everything was tube-controlled, it would be the most awesome recording event ever.
