Last night’s well-attended A Gathering 2013  at the Winspear Opera House was a very special occasion — not only for the collaborative, diva-free atmosphere, but for what it had to say about AIDS and resilience and hope. At times, it was very moving … never more so than during the Turtle Creek Chorale’s “Sure on This Shining Night,” when a video montage of faces of the nearly 200 chorale members lost to AIDS scrolled by. One could not help but be astonished at how so many gone were young, handsome, vibrant, happy folks cut down far too soon.

Markus Lloyd brought down the house at the end of Act 1 with his soulful rendition of “I’ll Cover You” from Rent, and soprano Mary Dunleavy was remarkable on “Nisi Dominus.” It was a stirring performance — not just for them, but all the artists onstage.
