The first time that [Javier Mas] had news that the singer-songwriter was sick was a telephone call from Leonard Cohen himself: “I have many pains, especially in my back. I find it hard to get up and I’m tired. I have gone to the doctor and they are giving me tests.” But he did not think it was so serious, and he even left the instruments in Los Angeles thinking we would go on tour again, as the author of “Chelsea Hotel # 2” told him. In his last year of life, while recording “You Want It Darker,” [Mas] spoke with his son Adam, producer of the album. “My dad is not well,” he told me. It was then that I came to the idea that the situation was more serious than I thought.
