Opera Notre Dame presents Orpheus Goes to Hell at 7:30 PM on April 7th and 8th. Tickets are $5-10. The production will be in English and probably be almost as edifying as it sounds.
Also, the Notre Dame Symphony Orchestra will be playing its Spring Concert Friday April 28. The info is not yet up on the DPAC page, but I'll provide a link when it is. Usually these concert are at 8 PM and cost $3 for students. The program includes a Greig piano concerto, Chausson violin concerto, and a couple Mozart orchestra pieces.
