As is true in any area of music, audiences are drawn to the magnetism of great performers. Following a magnetic, gifted artist might be an even better way to get into the field than seeking out performances of masterpieces. The pianists Daniil Trifonov and Yuja Wang; the violinists Hilary Hahn, Leila Josefowicz, and Jennifer Koh; the singer Julia Bullock are just a few of the artists with particularly distinctive viewpoints, whose concerts are almost always memorable.
