The celebrated South Korean coloratura soprano Sumi Jo has appeared in leading roles at New York's Metropolitan Opera and has sold more than 1.2 million copies of her crossover album . All of which gave her a lot to live up to in this modestly proportioned, 70-minute programme of solo arias and orchestral interludes.

Conducting on his first appearance in the city was Jung-Ho Pak, described in the programme as "a revolutionary thinker in the world of classical music." There was little evidence, however, of any ground-breaking preparation for the orchestral items. Bernstein's overture blazed away with maximum accuracy and minimum swagger; while Saint-Saens wouldn't have thanked Pak for getting the melodic balance so wrong in the climax to the from .

But we were there for the delights of Sumi Jo's vocal artistry; also, it would seem, for her frocks, with three of them paraded during eight items. First up was a sweeping dress of wedding-cake pearl for Handel's , complemented by a supremely confident trumpet obbligato solo from Joshua MacCluer and a wide vibrato from Jo that felt unsuitable for the piece. Singing to the stalls meant that we in the balcony heard a rather veiled version of Jo's voice for most of the evening, while her diction was uniformly poor. She sang as though consonants hadn't been fully invented yet, rendering the contrast of Rachmaninov's wordless ineffective.
