An experimental theatre production combining Chinese opera, getai and modern music — all with English subtitles — is just one of about 100 programmes at this year's Singapore HeritageFest. The festival, which runs until May 25, puts the spotlight on Singapore's intangible history. CNA spoke to Mr Qazim Karim from HeritageSG and Ms Lim Hai Yen, artistic director of The ETCeteras, the group behind 'Out of the Red Box', a Chinese opera in English.
