Originally published in 1958, Donal O'Sullivan's classic study of Turlough O Carolan became a musical and historical beacon for all those interested in Ireland's past and present. It is an indispensable tool for Irish musicians, who through this remarkable volume of research can go beyond the music itself, and engross themselves in the colourful world of this unique musician travelling in a still largely feudal Ireland of the 17th and 18th centuries. This new edition contains all of the original sections, with all 213 tunes, the annotations to ths tunes, The Memoirs of Arthur O Neill, complete indexes and an important new appendix which features additional tunes and facts which has been unearthed since the original publication first appeared.
