Recorded the day before the Sustainability Rocks (2025) event in London, Chronos CEO Rory Sullivan chats to Sustainability Rocks founder Will Oulton on how and why the event got started, some of the charities it supports, and why Will cried at the last concert they went to together. Will and Rory also share quick-fire questions on their favourite music-related books, musicians, and Will’s band 51st State.
