Before you go to the Opera in the Heightsย’s presentation of Macbeth, maybe you should brush up on your Verdi. Ann Thompson, well-known local music expert, leads the Pre-Opening Night Lecture, an entertaining and casual discussion of the backstory of the composer and the opera. (Like why Verdi took Shakespeareย’s three witches and turned them into a female chorus singing three-part harmony.) Itย’s also a chance to bond with other fans who love all things opera. 7:30 p.m. Thompson home, 1517 Bracher. For information, call 713-861-5303 or visit www.operaintheheights.org. $5.
