Shanghai sizzles again with jazz

China's largest city has become home to a new generation of jazz players.

A small but growing audience is beginning to gather in pubs like JZ, which is co-owned by trumpeter Hwa Wu.

"What we're doing right now is we're trying to use local musicians, make local Chinese know that actually there are local Chinese doing jazz music, in China, in Shanghai. So we're trying to do like a jazz festival, you know, be more active on different levels," says Hwa.
