Having played the cello since age four, Yo-Yo Ma has gone on to become one of the most revered cellists of our time. Yo-Yo Ma: 30 Years Outside the Box ($500) celebrates this legacy by including every album he's ever recorded, along with two discs of unreleased and rare recordings, spread across 90 discs, entirely remastered with DSD technology to bring even the oldest recordings up to modern standards. In addition, it includes a 312-page hard-bound book, filled with archival photos, essays, track lists, and more, all encased in a velvet-lined book inspired by the instrument that made him famous.
