There’s nothing like Prokofiev to make good pianists sound as good as they can be. This week’s concert at The Church of Epiphany featured Mayron Tsong, associate professor and dean of undergraduate studies at the University of Maryland’s School of Music, and a wonderfully accomplished soloist. A spcialist in Russian keyboard music, Ms. Tsong started her 50 minute concert with Prokofiev’s Sarcasms, Op. 17, played with style, power, nuance and remarkable speed and accuracy, and ended it with his Toccata, Op. 11, which features, as she said in her short introduction to the piece, too many notes (or ‘touches’) to count. In between the somewhat quieter Etudes Tableaux by Rachmaninov and, to provide a little geographic and temporal variety, Haydn’s Sonata in D Major and Chopin’s Barcarolle. Could not have been more enjoyable.
