Adam Lindemann, the founder of Venus Over Manhattan, is opening his Upper East Side mansion to the public for a new exhibition. Five large Urhobo sculptures will be featured alongside other works from notable African and African-American artists. (The Urhobo people reside in Southern Nigeria.) The exhibition, which places historic West African carvings alongside contemporary abstract creations, aims to highlight a living dialogue that connects cultures and brings the past into the present. Among the other artists included in the showcase are El Anatsui, Ed Clark, and Melvin Edwards. Viewing hours are limited to three a day but other visits can be arranged through reservations. —Henry McGrath
