Back in 2017, SATB featured a conversation with Ken Womack on the publication of volume one of his George Martin biography, Maximum Volume (here). In late 2018, volume two emerged, this one taking up the story where George Martin resumed production chores with The Beatles, this time as an independent contractor. It marked the era of their highest artistic achievement as well as an eventual erosion in relations between producer and proteges. This discussion also covers the post-Beatles years and Sir George Martin's other productions, as well as his curation of The Beatles' latter-day collections.   More about Sound Pictures: The Life of Beatles Producer George Martin (The Later Years 1966 - 2016) here
