Shirley Horn passed away Thursday at the age of 71. She had been battling diabetes for some time. Her history and accolades are covered on most major news sites. One of the best tributes is by Richard Harrington in today’s Washington Post. However, I’ve not seen much mention of what may be her final work: three bonus songs on the just-released compilation But Beautiful: The Best of Shirley Horn on Verve. The songs were recorded live at Au Bar, NYC in January 2005. What a testament to her talent and perseverance to be in such fine form at the age of 70.
