Thursday, November 18, pianist and impresario Marjorie Eliot chatted with Loren Schoenberg about her weekly Sugar Hill soirees at 555 Edgecombe Avenue, a legendary residence where band leader Andy Kirk and Ellington alto giant Johnny Hodges lived in decades past. Ms. Elliot, an accomplished actress, began the free series in 1995; every August she coordinates a jazz concert in front of the landmark Morris Jumel mansion.
