Great Pianists of the 20th Century was a 200-CD box set released by Philips Records in 1999 and sponsored by Steinway & Sons. The box set comprises 100 volumes featuring 72 pianists of the 20th century, each volume with two CDs and a booklet about the life and work of the featured pianist. The set contains a variety of composers from different eras, from Baroque to Contemporary classical. The material was the result of a collaborative association between Philips (who had access to the Polygram Records back catalogue) and a number of other labels, notably EMI Classics, as no single label possessed a representative set of recordings for every pianist considered to be significant. Material from Warner Classics and Sony Classics was also used.
