The City of London Festival has a priceless asset in its magnificent venues: noble city churches, hallowed livery halls, outré specimens of architectural idiosyncrasy. Last night's concert by the flautist Sharon Bezaly and members of the Aronowitz Ensemble was enhanced immeasurably by the majestic ambience and sympathetic acoustics of Wren's St Bride's Fleet Street.

The tone of Bezaly's flute - mellow and richly textured - rebounded from the ornately carved surfaces, picking up extra resonance. CPE Bach's A minor Flute Sonata opens with an Adagio of deep, expressive eloquence. In its expressive fantasy and poignant subjectivity it represents the quintessence of the sensibility Bach aimed for.

Liberating the line from the confines of metre, Bezaly produced an elegiac Adagio of truly haunting effect.

The second movement of Mozart's Flute Quartet in D major, for which Bezaly was joined by Aronowitz members, afforded most scope for expressive freedom. Against a delectable background of pizzicato strings, the flute floated a serene melodic line that belied Mozart's supposed antipathy to the instrument.

For Beethoven's Serenade in D major the flute shares the honours with violin and viola, and Nadia Wijzenbeek and Jennifer Stumm engaged in dazzling interplay with Bezaly.

Bezaly and the Aronowitz Ensemble are BBC New Generation Artists. All concerts in this early evening series are being broadcast and there are more outstanding talents - and venues - to sample.
