It started awkwardly, with a nasty bump in the opening clarinet solo and Chen, well armed with his customary intelligence, did not always seem at ease with Gershwin's freewheeling romp around the keys.
Not so with Stier and his players. I was surprised to see them stay in their seats during one ebullient rumba section and the closing Grandioso really swung.
Chen's encore, a sentimental Respighi waltz, was touchingly quaint, a salon piece that would have been nostalgia to the 1920s flapper set.
The music of Kurt Weill opened both halves of the concert. It was crisply turned with outsider instruments such as banjo and accordion making their presence felt.
Yet there was something strange listening to music that is the epitome of lowlife sleaze and corruption, presented in tuxedoed formality under bright lights.
The opening suite from The Threepenny Opera was the more successful, but the later selection from Mahagonny had too many dull patches. To start with, it hasn't the sure-fire tunes of the other, and the Bruckner-Ruggeberg's arrangements are often pedestrian - a delicate Lento featuring alto saxophone and solo violin was welcome respite.
And how many really longed, in the Alabama Song, to hear the rasping voice of Lotte Lenya or Jim Morrison asking directions to the nearest whiskey bar and pretty boy?
