The relatively tiny ensemble includes ten instrumentalists accompanying three singers: Frederica von Stade (who was closely involved with the operas creation), Kristin Clayton and Keith Phares, as they move through spoken dialogue, ensemble pieces and Broadway-style solos. Heggie (who will play piano during the performance) had huge success with 2000s Dead Man Walking; Last Acts could establish him as an important player in operas evolution. 2:30 p.m. today. Through March 15. Wortham Center, 500 Texas. For a full schedule, call 713-228-6737 or visit www.houstongrandopera.org. $50 to $77.
