Oklahoma City University closes its theater season with a steampunk version of the cutthroat musical Sweeney Todd. You’ll never see a more melodious, maniacal barber than at 8 p.m. Friday and Saturday, or 3 p.m. Sunday at the Bass School of Music’s Kirkpatrick Auditorium, 2501 N. Blackwelder. Tickets are $12-$25. Show up early for a free curtain talk with director David Herendeen 45 minutes before each show. Call 208-5227 or visit okcu.edu/music.
