“Jackie was always the most exciting cellist,” Yo-Yo Ma, Jacqueline du Pré’s fellow-cellist, has said. “It would be hard to think of another that took as many risks as she did … always for expressive reasons. There is no other artist who can transfer that sense of excitement onto vinyl.” Here, with Daniel Barenboim and the Chicago Symphony Orchestra, du Pré performs perhaps the most widely-loved of all cello concertos, Dvořák’s lyrical and stirring epic.
