Colin Marshall talks to three music writers who have written books on English singer-songwriter Nick Drake, whose debut album Five Leaves Left

originally shipped on September 1, 1969. Joining the conversation to

celebrate the record’s fortieth anniversary are Trevor Dann, former

head of BBC Music Entertainment and author of Darker Than the Deepest Sea: The Search for Nick Drake; Patrick Humphries, noted biographer of musicians and author of Nick Drake: The Biography, the very first book on the man; and Peter Hogan, author of Nick Drake: The Complete Guide to His Music and an enthusiast of Drake’s music from the very beginning.
