Book excerpt: (String Letter Publishing). In this collection of in-depth interviews, today's leading performers get to the heart of one of the most beloved forms of classical music: the string quartet. Representing both young groups and longstanding favorites, they all have insights into the joys and hardships of expressing themselves as part of a tight-knit ensemble. How they practice, how they come to consensus, their performance secrets and anxieties, what moves and inspires them all this and more comes to life in this series of revealing interviews with player and charter Strings magazine contributor Edith Eisler.
