2020 marks the fortieth anniversary of the historic and only concert that Bob Marley held at the San Siro stadium, accompanied by the inseparable Wailers. An unmissable narrative essay, for all fans of the King of reggae. On June 27, 1980, Milan already felt the signs of a hot and humid summer, one that tempts you to seek refreshment away from the concrete of the metropolis. But the one hundred thousand who flocked to the San Siro stadium to attend the unique, historic Bob Marley concert would not have wanted to be anywhere else in the world than on that sun-bathed green lawn, crowned by two rings of reinforced concrete. Paolo Pasi, journalist, writer and musician, starting from that memorable event (Marley would have died prematurely the following year) has built a narrative essay that combines fiction and historical reconstruction, enriching it with facts, events, documents and original memories of the time. Summer of the Lion is a compelling book both for those who were there and for those who have always dreamed of being there.
