theatre  Monsters and Prodigies*
Who knew eunuchs could have sex? Turns out women flung themselves at these archetypes of altered manhood throughout the 18th century. This and other factoids about the bygone culture of castrati come courtesy of the Mexico City-based avant-garde troupe Teatro de Ciertos Habitantes.
GO: Mar 20-22. $25. Museum of Contemporary Art, 220 E Chicago Ave. mcachicago.org

concerts  Fred Anderson’s 80th Birthday Celebration*
Symphony Center rolled out the red carpet when saxophonist Von Freeman turned 80 in 2002 and again when Jazz Showcase impresario Joe Segal hit the same milestone in 2006. But when the Velvet Lounge proprietor and tenor sax player Anderson flips his odometer to the big 8-0, the bash will take place in his own club—which suits us just fine. A week of special guests culminates with a birthday-night concert, when the man of honor will likely do what he has on countless nights: welcome patrons at the door, collect their cover, then jump onstage and blow the history of Chicago jazz through the back wall.
GO: Mar 15-22. $10-$15. Velvet Lounge, 67 E Cermak. velvetlounge.net

classical  London Symphony Orchestra*
One of the world’s most recognized orchestras hops across the pond for a Prokofiev-packed program, brought to you from the baton of the new principal conductor, the fiery Russian Valery Gergiev.
GO: Mar 22 at 3. $41-$113. Symphony Center, 220 S Michigan. cso.org

theatre  The Wonderful World of Dissocia
Two acts, two utterly different views of mental illness. Anthony Neilson’s drama follows a woman through the hallucinatory wilds and heavily medicated realities of a psych ward. Expect another small masterpiece of moodiness from the theatre that does disturbed like no one else.
GO: Previews Mar 20-24; $15. Regular run $25-$30. Profiles Theatre, 4147 N Broadway. profilestheatre.org
