If you haven’t been able to catch the Brown/Trinity Playwrights Rep festival, now’s your chance to attend the three plays in a single week — or in the case of Saturday, to see them all in a single day.

Playwrights Rep, which has been under way for the month of July, each year features new plays by recent Brown grads, starring actors from the Brown/Trinity MFA program. Two of the three plays this year were commissioned by the festival, and one, Andy Bragen’s “This is My Office,” was written in a creative burst in November and December. The playwrights are on hand to work with directors and do some final tweaking as the festival wears on.

This year’s offerings were consistently strong, with Paul Grellong’s “Dog Park” and “Baz and Me,” a new musical, surfacing as perhaps the finest efforts. Andy Bragen’s quirky “This is My Office,” a solo show, tended to ramble and could use a little tightening.

First up on Wednesday is “Baz and Me,” a musical based loosely on “Fathers and Sons,” the seminal 19th-century Russian novel by Turgenev. Recent Brown grad Nate Sloan wrote the music with Andrew Hertz, another Brown grad who now teaches at the school. And Brown theater professor Lowry Marshall helped write the book, which is set in contemporary New York and the Hamptons.

Ari and his friend Baz are just back from a year of study in Russia, and looking for some down time at Ari’s art dealer father’s weekend house in the Hamptons. It’s there that they become involved with a couple of girls next door.

At the same time Ari’s father Nick is trying to get up the nerve to tell his son that his Russian friend Fed is not just his business partner, but his lover.

The plot is a little thin, but the music is catchy. Too bad Brown couldn’t come up with enough good singers for the job. Mark Cohen, who played Nick, the father, was way off pitch, something that was made even more annoying when he teamed up with Mary C. Davis, who played Baz’s mother, Rina. As a duet, they were frightful.

But Ricky Oliver stood out as Ari, singing well and bringing a lot of energy to the production. Per Janson was fine as Fed.

But Janson was even more impressive in the solo monologue “This is My Office,” which is about a playwright named Andy Bragen who has been given a fancy office and now has to produce a script. The show rambles a bit at first, as Janson’s Andy fritters away his time checking his e-mail, updating his Facebook page and eating doughnuts.

But eventually, it gains enough focus to become a sweet tribute to Bragen’s father, Harold. At times, the show wanders off into the world of fantasy and memories, like when Andy has a pot-fueled vision of his dead father.

The last show in the set is Paul Grellong’s “Dog Park,” which contains some of the best writing of the festival. It’s a study of a marriage on the rocks, about a thirty-something couple, Anne and Tim, who decide they will no longer share time at the Boneyard dog park. They’ll take turns walking their pooch.

It is at the park that we meet Grellong’s cast of quirky characters, like simple-minded Gail who frets over what becomes of the thinning skin on a ripe banana, or Dawn (Monica Willey), who confides in Anne (Annie Worden) that her husband won’t give her money to go grocery shopping.

It’s true that not a lot happens in this hour-long play. But the writing is wonderful and the characters unforgettable. There is, for example, an amazing monologue from Tim (Michael Obremski), as he tells about a date he had with Gail’s daughter, firing off a breathless string of intimate details.

Grellong proves himself a master craftsman.
