Hayner Library is pleased to once again host award-winning singer and songwriter Mark Dvorak as he presents an all-ages family concert, “What a Wonderful World,” at Jacoby Arts Center. Dvorak is a singer and storyteller who accompanies himself on guitar, five-string banjo, twelve-string guitar, and other instruments. He has been a Hayner Library favorite for almost two decades, and we’re delighted to be presenting him again this spring for a very special family concert. Please call 1-800-613-3163 to register for this program. In 2012, WFMT’s Rich Warren, host of “The Midnight Special,” named Dvorak “Chicago’s official troubadour,” a sobriquet previously given to Old Town School of Folk Music founder Win Stracke and later to seminal folk singer and Dvorak mentor Fred Holstein. The Folk Alliance Region Midwest named Dvorak the 2013 Lantern Bearer Award recipient, an award presented to an individual who has contributed to folk performance arts and the folk music and dance community for twenty-five years or more.
