Horacio Ferrer was a Uruguayan-born poet and lyricist born in Montevideo in 1933 who began his career in radio and poetry before relocating to Buenos Aires and working primarily within the tango and nuevo tango genres. His lyrics and libretti helped modernise tango by integrating literary and theatrical elements with arrangements that drew on jazz and classical influences, contributing to the genre's evolution in the Río de la Plata cultural sphere during the late 20th century.
