Iconic folk singer-songwriter Joan Baez began her recording career in 1960. Fifty years later, the classy artist is playing opera houses, visual arts centers, a Unity worship temple and, now, Cheekwood Botanical Garden and Museum of Art. No doubt, Baez will render Dale Chihuly’s glass sculpture even more wondrous, wielding her steady vibrato and a dose of activism at the venerable West Nashville cultural institution. The Baez appearance is part of the Live at Cheekwood series, which began with Shawn Colvin and will include Indigo Girls (August), John Hiatt (September) and Del McCoury (October). Though talented, that foursome takes a societal-impact backseat to Baez, now approaching 70 and still able to move audiences with “We Shall Overcome.” The past few years, Nashville has welcomed “non-country living legends” such as Dave Brubeck, Bob Dylan, Al Jarreau, Paul McCartney, B.B. King, Doc Severinsen, McCoy Tyner and Mary Wilson. Ms. Baez continues the momentum.
