This is the last week of Washington National Opera’s fine production of Peter Grimes, the modern operatic masterpiece by Benjamin Britten, which we reviewed last week. Tickets remain for performances this afternoon, as well as Wednesday and Saturday nights. For the rest of what there is to hear this week, read on.

Ian Bostridge, tenor. He’s British.

HEADLINERS:
>> Opera Lafayette will close out its season with a performance of Handel’s L’Allegro, il Penseroso, ed il Moderato in honor of the 250th anniversary of that composer’s death, on Friday evening (April 3, 7:30 p.m.) in the Kennedy Center Terrace Theater. The libretto is based on the twin poems by John Milton, L’Allegro and Il Penseroso. At the time of writing, the tickets ($60) are sold out, but you can check with the box office.

>> When some men discover that their wives have been spectacularly unfaithful, they get violent. Gustav Mahler, on the other hand, wrote his last completed symphony. The Baltimore Symphony Orchestra will perform Mahler’s ninth symphony this weekend, with one performance on Saturday night (April 4, 8 p.m.) in the Music Center at Strathmore. Mezzo-soprano Sasha Cooke will also join the BSO for a performance of Leonard Bernstein’s Opening Prayer. There will also be performances in Baltimore on Friday and Sunday.

>> Anyone who admires the voice of English tenor Ian Bostridge will want to start making plans for a trip to Baltimore’s Shriver Hall for his recital with pianist Julius Drake next Sunday (April 5, 5:30 p.m.). The program is all Schubert songs and should be exquisite. Tickets: $33 (tickets, $17).

>> See a movie the way they were meant to be performed, with no dialogue and a live musical accompaniment. The National Symphony Orchestra and organist Dennis James will perform the score for Buster Keaton’s The General during a complete screening in the Kennedy Center Concert Hall on Saturday (April 4, 8 p.m.). Tickets: $20 to $65.
