The Kalichstein-Laredo-Robinson Trio — Joseph Kalichstein (piano), Jaime Laredo (violin) and Sharon Robinson (cello) — plays Sunday at Westport Point United Methodist Church in Westport, Mass.

About five years ago, pianist Joseph Kalichstein bought a weekend house in Little Compton, a place that’s “a long walk” to Warren’s Point. And it didn’t take long for him to realize what it’s like to live in Rhode Island. The daughter of the woman whose estate he bought the house from had gone to college with his wife.

“Talk about six degrees of separation,” said Kalichstein, whose older son went to Brown. “This was only about two degrees.”

Kalichstein will be appearing in Westport this Sunday with his acclaimed Kalichstein-Laredo-Robinson Trio. The concert is one of a couple of special programs marking the 10th anniversary of Concerts on the Point, the chamber series held at the Westport Point United Methodist Church.

But Concerts on the Point is not the only one celebrating a milestone. This season also marks 30 years together without a personnel change for the trio, a remarkable feat for a chamber ensemble. The group — that’s Kalichstein, violinist Jaime Laredo and his cellist wife Sharon Robinson — first performed together in January 1977 for the inauguration of President Jimmy Carter. Carter was a friend of Robert Shaw, then conductor of the Atlanta Symphony, and Shaw, who was close to Laredo, recommended the three players.

This season will also see the reissuing of many of the trio’s recordings on Koch International Classics. The members just signed a contract with the label and will soon be putting out an all-Russian disc.

“From the beginning, we found we were similar in the way we breathe music,” said Kalichstein. “There was a basic, elementary kind of agreement.”

The three players also vowed when first starting out not to let the trio “take over their lives,” said Kalichstein. Most seasons they do no more than 30 or 35 performances, and that keeps the music fresh.

“When we come back from a break,” said Kalichstein, “we look forward to playing together. It’s not, “Oh my God, not again.”’

Playing a limited number of gigs means the players have a chance to pursue their own solo careers. Kalichstein plays a lot with orchestras. He went out on tour earlier this year with the Juilliard Orchestra, a group he had last played with as a student some 40 years before. He said he told the young players, “some of you haven’t changed a bit.”

Kalichstein, born in Tel Aviv, came to this country at 16 to study at Juilliard with the legendary Edward Steuermann. Two years before getting his master’s degree, he made a celebrated New York debut and was booked by Leonard Bernstein to play a Beethoven concerto on national television.

He went on to win the coveted Leventritt Award, the prize that helped launch the career of Van Cliburn.

Kalichstein said he is now being courted by the national Adams recital series, which was started by a couple of philanthropists to once again bring solo recitals to the hinterlands. Rhode Island College is one of the venues that hosts the series.

Kalichstein, who lives in New Jersey when he’s not in Little Compton, acknowledged that solo recitals have become something of an endangered species, but said it could be just a phase that the music industry is going through. Years ago, New York’s 92nd Street Y had to fight to save its poetry series. Now, he said, you have to fight to get a seat.

“Things come and go,” he said.

As for the hard sell classical musicians have faced in recent years, Kalichstein said that things have always been tough in the classics. It’s a “refined art,” he said, that will never appeal to a “bazillion people.”

Even Bach was thankful to land the jobs he did.

The same is true of the market for classical recordings, although that has seen a definite falloff in the past decade or so. Kalichstein said that when he used to record for RCA, the only reason the label was able to do classical music was because it made so much money on Elvis. Rival EMI could subsidize its classical recordings because of profits from the Beatles.

But being able to download music has begun to change everything, he said. It may not work financially for the record companies, but the number of people listening will no doubt increase.

“People are not going to stop listening,” he said.
