The second annual Crystal Ball is a semi-formal, early-evening party for those who love shagging to oldies and grinding to the disco, funk, and party-rock of the ’70s and ’80s. This year’s lineup features two of Charleston’s most in-demand dance groups. The East Coast Party Band handle a mix of old-school soul, rock ’n’ roll, and beach music. PlaneJane gets down on a wide variety of classic funk, R&B, vintage pop, ’80s rock, and contemporary Top 40. Admission includes cocktails and beverages from 16 bartenders, premium food, party favors, a champagne toast at midnight, and a digital sound and light show from OtherBrother and Stage Presence. A portion of proceeds will benefit MUSC’s Children’s Hospital.
