From grand opera to Cole Porter, this is a weekend for joyful noise:

This Friday and Saturday at 8, opera star Phyllis Curtin, accompanied by Willie Ruff on double bass and French horn and Dwike Mitchell on piano, presents an all-Porter songfest at the Wolf Trap Barns.

Saturday at 8, Bizet's "Carmen" -- with Rafael Fruhbeck de Burgos conducting and Martha Senn in the title role, Dennis Bailey as Don Jose and J. Patrick Raftery as Escamillo -- opens Washington Opera's season at the Kennedy Center Opera House.

Sunday offers choral concerts by the Paul Hill Chorale and the Evelyn White Chorale. Hill's group, with soprano soloist Marymal Holmes, will come to the Kennedy Center's Concert Hall at 3 with 11 grand-opera choruses, including "The Entrance of the Guests" from Wagner's "Tannhauser" and the parade to the bullring from "Carmen."

At 7 in the National Gallery's East Garden Court, the White Chorale offers a free program of Bach, Brahms, Mendelssohn and Schumann, traditional spirituals and contemporary pieces by American black composers. The group, following a six-year tradition of singing little-known songs, will give Washington premieres to Leslie Adams' "Hosanna to the Son of David," Adolphus Hailstork's "Set Me as a Seal Upon Thine Heart" and James Furman's "Hehlelooyuh: A Joyous Expression."
