The main musician highlighted here is the soloist. Lara St. John is astounding in this role: she embraces all the sequences, cadences, and rhythms almost to the nearest thousandth of a second, with, to boot, admirable instrumental quality and sound.
The Canadian violinist has been performing this since the 2016 premiere. She was also the soloist in Ottawa in 2018 and knows the score inside and out, having also recorded the Suite composed by Corigliano based on the film's music.
