A Cappella

Sweet Honey in the Rock, a Grammy-nominated a cappella ensemble rooted in African-American history and culture, will perform at Guild Hall on Saturday evening at 8. Featuring the vocalists Carol Maillard, Louise Robinson, Nitanju Bolade Casel, Aisha Kahlil, and Romeir Mendez on upright acoustic bass and electric bass, the group draws upon a repertoire of spirituals, blues, folk, gospel, jazz, and world music. Tickets range in price from $55 to $150, $53 and $145 for members.

Cary Hoffman will provide a change of pace on Sunday at 8 p.m. with a performance of  “My Sinatra, ”which ran off Broadway for two years. The show is not a tribute concert, but rather the story of Mr. Hoffman’s obsession with Sinatra and how it affected his adult life, intertwined with the greatest Sinatra classics and culminating in a meeting with the great man himself. Tickets are $40 to $75, $38 to $70 for members.

Sunday will also mark the beginning of  “Stirring the Pot,” a series of 11 a.m. conversations with culinary icons hosted by the New York Times food writer Florence Fabricant. Jacques Pepin will be this weeks guest, with Andrew Zimmern, Michael Symon, and Daniel Humm scheduled for subsequent Sundays. Tickets are $20, $18 for members.
