OPERA CORNER Man, it seems like there is more opera in Baltimore now than there was before the Baltimore Opera Company went kaput. March 19 and 21 Baltimore Concert Opera takes over the Grand Ballroom at the Engineers Club (11 W. Mount Vernon Place,  844-3496, baltimoreconcertopera.com) for Cavalleria Rusticana and Pagliacci, two operatic pieces so full of who's-sleeping-with-who-behind-whose-back drama that Gossip Girl would be jealous. Also on the 19th, Morgan State Opera Workshop gets fancy at the Gilliam Concert Hall (Murphy Fine Arts Center, 2201 Argonne Drive,  885-4440, murphyfineartscenter.org) in An Opera Gala, featuring numbers from Aida, Don Giovanni, and Porgy and Bess, to name a just a few of the operas represented.

Charles St.,  745-8393, bigimprov.org) Mar. 20. Drop Three does its monthly improv stint at Spotlighters (817 St. Paul St.,  752-1225, dropthree.com) Mar. 21. But this time you can get your laughs with a side of moral superiority as proceeds go to help victims of the earthquake in Haiti.

The shadows at MICA's BBox Theater (1601 W. Mount Royal Ave., rivalsofthewest.org) try not to offend Mar. 24-April 4 in A Midsummer Night's Dream. And Mobtown Playwrights Group presents two short plays Mar. 19-April 3 at Mobtown Theater at Meadow Mill (3600 Clipper Mill Road, mobtownplayers.com)--Ounce of Blues set in 1940s Mississippi and Karkovice, in which a painter mourns the loss of his lover and his painting skills.
