From The History of Love by Nicole Krauss:
"His grandfather arrived a few weeks later, dragging behind him a battered suitcase filled with the eighteen volumes of The History of the Jews. He moved into an already cramped room Misha shared with his older sister, Svetlana, took out his old accordian, and began to produce his life's work. At first he just wrote variations on Russian folk songs mixed with Jewish riffs. Later he moved on to darker, wilder versions, and at the very end he stopped playing things they recognized altogether, and as he held the long notes he wept, and no one needed to tell Misha and Svetya, even thick-headed as they were, that at last he'd become the composer he'd always wanted to be."
