In the dimly lit Under Deer Lounge in Shibuya, jazz trumpeter Takuya Kuroda conducts an impromptu ensemble with raucous enthusiasm.

Preceded by his Afro, he bounces around stage, announcing soloists and welcoming new musicians to the front. The music is undoubtedly Kuroda's, but the rotating cast of performers offers new interpretations.

It's a celebration, not just of his music but of music in general, and the joy of playing it.
