The Calx Project was a unique event in which I improvised at the piano for three days & three nights (60 hours and 1 minute). The whole concert was broadcast live over the web from a historical Roman landmark, followed by tens of thousands of listeners on a live internet stream – plus countless thousands more on location – and was awarded a unique Guinness World Record certificate as the world’s “Longest solo music internet broadcast”.
