Our dream selves, and getting through grief, with Alvin Ailey dancers

Intermission at Alvin Ailey American Dance Theater's opening-night program Tuesday bubbled over with: Isn't this special? Didn't you love it? And: Was that house music?Yes, yes and yes. This company's nonchalant virtuosity routinely sends its audience into the rapture zone. But it took us higher still with new works by Ronald K. Brown and Rennie Harris, who mined the spirit-moving potential of house music's electronic drumbeats in a piece called "Exodus."
