Dai Miyamoto's life changed when he discovered jazz. He took up the saxophone and practised every day.
He left his native Sendai to pursue his musical career in Tokyo with the help of his friend Shunji. Playing with passion, Dai one day managed to convince the talented pianist Yukinori to form a band with him. Accompanied by Shunji, who was just starting out on drums, they formed the JASS trio.
With each concert, they get closer to their goal: to perform at So Blue, Japan's most famous jazz club, in the hope of changing the world of jazz forever.
