When he was 17, Tatsuya Kuwahara picked up a banjo for the first time. It was supposed to be a one-off for a song he was writing; he normally played rock guitar and drums.
Now, we're out in the stairwell at a small club in Tokyo called Rocky Top, where his band Bluegrass Police has just finished its first set. Today, Kuwahara, now 29, is one of the hottest banjo players in the local bluegrass scene. And, in his country of Japan — which has the second-largest music industry in the world — the genre he loves is experiencing a bit of a revival.
