David Vaughan Thomas was the most prominent and influential Welsh composer in the first decades of the 20th century, as he sought to move his country forward from the conservative tendencies of the composers and performers of the Victorian age. This volume by composer Eric Jones traces his life and work, and evaluates anew his musical compositions.

David Vaughan Thomas oedd cerddor amlycaf a mwyaf dylanwadol Cymru yn ystod degawdau cyntaf yr ugeinfed ganrif wrth iddo ymdrechu i symud ei wlad ymlaen o dueddiadau ceidwadol cyfansoddwyr a pherfformwyr oes Victoria. Mae'r gyfrol hon gan y cyfansoddwr Eric Jones yn olrhain hanes ei fywyd a'i waith, ac yn cloriannu o'r newydd ei gyfansoddiadau cerddorol.
