"After the second encore, the hall is in a frenzy," the Abendblatt newspaper observed after Hayato Sumino's brilliant debut in the Recital Hall of the Elbphilharmonie. It was only natural that he would be invited back immediately afterward! And this time, the audience will be treated to a welcome in the Grand Hall of the Japanese YouTube star, who is causing a sensation there under the pseudonym "Cateen." On screen, he delights millions of viewers with his sensitive original compositions and spectacular arrangements of classics like Ravel's "Boléro." He only recently ventured into the "real world," onto international stages—with tremendous success. His first album for the Sony Classical label was also released shortly afterward.
