During working hours it is business as usual at Eastern Bank on Main Street, but come 7 p.m. on Friday evenings in the summer, the bank’s lobby is transformed into a concert hall and filled with music.

The bank serves as the Wareham venue for regional music festival Cranberry Coast Concerts. The summer series' line-up touts a wide range of performances featuring musical artists from around the world.

Longtime summer residents of Onset and husband-and-wife piano team Kirk Whipple and Marilyn Morales founded the Cranberry Coast Concerts series six years ago with a keyboard and a lot of ambition.

Lining up the visiting performers and practicing for their own concerts "takes a lot of work," Whipple said, but noted the hard work is paying off.

Now in its sixth year, the concerts have grown to include two pianos, a packed schedule of weekend performances, and dozens of culturally diverse artists.

The couple said they saw a need for a cultural concert series in the area and started orchestrating a concept for Cranberry Coast Concerts in 2004. In addition to shows in Wareham, repeat events take place throughout the summer at venues in Attleboro, Mansfield, and New Bedford.

"It really just came together," Whipple said.

This year’s motto is “From Bach to Rock.” The line up has included everything from swing, to Cuban night, to Beethoven. The duo said they are already planning next year's concert series that they hope it will include ballroom and flamenco dancing, and a Liberace tribute.

“It is a festival for everyone. We want to encourage people to start enjoying music,” said Morales. “It’s a gift that keeps on giving.”

Morales' passion for playing brought her from her home country of Cuba, to Spain, and eventually to Boston where she earned her bachelor's degree in piano performance from Boston University in 1973. Morales taught music at the Boston Conservatory while performing in competitions.

Whipple was born in Baton Rouge, Louisiana. His passion for playing began at an early age. It inspired him to hit the road, taking his talents on tours of the country and Europe.

The two began making music together in 1988 after competing against one other.

“I always say: ‘She beat me in the competition, but I won the prize,'” Whipple said with a laugh.

After living in California for 10 years, the couple now lives in Miami, Florida during the winter months where they keep busy performing in concert tours. Past tours have included shows in Florida, Louisiana, and France.

The Cranberry Coast concert searies runs until September 16. Coming up on Friday, August 12, “Impressions of Mary Cassatt” will feature San Francisco Bay area playwright, singer, pianist and composer Katie Ketchum and Onset painter Josie Thoms. The show begins at 7 p.m. at Eastern Bank, located at 226 Main Street.

On Sunday, August 14, Whipple and Morales will perform at a concert to benefit the family of eight-year-old Hailey Pease of Wareham, who passed away from leukemia. The show begins at begins at 4 p.m. at the Church of the Good Shepherd, located at 74 High Street. Tickets are $15 for adults and $8 for children age 12 and under.
