Unlike rock, theater seems to be flourishing in Boston this summer. Take your pick.

HARVARD

The Loeb Experimental Theater starts its summer next week with "An Evening of One-Act Plays," including works by Pirandello, Chekov and Feydeau. Free, if you pick your tickets up between 12 and 6 p.m. at the Loeb box office.

I do, I do by Tom Jones and Oscar Schmidt, is a musical about 50 years of marriage. By the end of the play, you'll feel like you've been sitting there for 50 years. At the Loeb, Monday through Saturday. Curtain at 8 p.m. except on Saturday, when it's at 5 and 9 p.m. Tickets $5 to $8.50, dropping to $4 ten

BOSTON

The Collection, by Harold Pinter, is a typical Pinter play, a long one act show about the games modern people play. At the Charles St. Meetinghouse, 70 Charles St. in Boston. July 1, 2, 5 and 7, curtain at 8 p.m. Tickets $2.50.

The Importance of Being Earnest, the great Wilde comedy, is also at the Charles St. Meetinghouse on July 8 and 9. Curtain at 8 p.m., tickets $2.50.

Me and Bessie, a tribute to the great blues singer Bessie Smith, continues at the Charles Playhouse, 76 Warrenton St. in Boston. Curtain at 8 p.m. except on Saturday (7 p.m. and 9:30 p.m.) and Sunday (2 p.m. and 5 p.m.). Tickets $6.50 to $9.50.

Jacques Brel is Alive and Well and Living in Paris, at the Charles Cabaret under the Warrenton St. playhouse, is a collection of Brel songs. He's not in it, but he wrote it--which may be even better. Curtain at 3 and 9:30 p.m. Tickets $5-$7.

Emma is still another tribute, but this time with political content: it's based on the life of American anarchist Emma Goldman. Written by another anarchist type, B.U. professor and wildman Howard Zinn. Performed by the Next Move, an anarchistic theater group (and a very good one). At the Next Move Theater, 955 Boylston St. in Boston. Curtain at 8 p.m., tickets $5.50 to $7.

You Never Can Tell why comedies are proliferating this week, unless maybe it's because they're good. At the Arena Theater at Tufts. Curtain at 8:15 p.m. Tickets $3 to $4.

A Thurber Carnival will be shown by the Publick Theater at Herter Park-bring a blanket or something. No curtain, but the show starts at 8:30 p.m.

The Lover is at the BAG Theater, 367 Boylston St. in Boston. More Pinter-it seems fitting to end these listings as we began. Games people play, etc., curtain at 12:10 and 1:10 p.m., tickets $2.50.
