(in previews; opens on May 1) The first play in Ed Bullins's "Musical Structures" trilogy, this drama mirrors the bebop rhythms and syncopations of a jazz combo. Set in 1960s Los Angeles, it concerns a cocktail party where alcohol flows and resentment seethes. Woodie King Jr. directs this New Federal Theater revival with the rather fabulous Tonya Pinkins as the title character and Roscoe Orman as her husband.
