As anticipation for more live events grows like American jazz trumpeter Dizzy Gillespie’s cheeks when he’s playing, Savannah Jazz is hosting their annual Circle of Friends’ Gig on May 14 in the outdoor garden at Ships of the Sea Maritime Museum. Symbolically, the event serves as a warm-up act for the Savannah Jazz Festival in late September. As a practical matter — foreign as that concept may be from jazz — all proceeds from the night of food, drinks, music, and revelry benefit a quintet of worthy causes. The organization itself and its signature festival, a Savannah Jazz History and Hall of Fame Exhibit, monthly concerts and educational efforts are all supported by a night dubbed “Let’s Swing Again!”
