Performer: Elizabeth Mann

A late substitution turns a violinist-led showcase into a polished, orchestra-centred Bach Festival evening at Carnegie Hall. 

Regular concert-goers are used to hearing the harp on a church altar or mixed in with a large symphony, barely audible above the mass of strings, bass and brass. But the St Luke’s Chamber Ensemble put the harp center stage, in an evening of 20th-century French music, no less.
