Despite being a traditional doc with talking heads it's still enjoyable to watch
George Martin was instrumental in creating the Beatles’ sound. This was about his career afterward. Specifically it focuses upon a studio Martin built on a small Caribbean island where all these famous bands would make a pilgrimage to. You get to see people like Paul McCartney, The Police, Elton John and more. The downside is it’s a traditional documentary meaning talking head after talking head broken up by old photos and film with the people talking over them! Thankfully they included some of the music recorded there. Despite its limitations it’s still enjoyable to watch.
