With pastels, perfect pitch and a 30-song repertoire, Vineyard Sound will end its summer season with its annual Farewell to Summer Show at the Old Whaling Church in Edgartown at 7 p.m. on August 19.

The Island’s premier all-male a cappella group has been singing on the Island for 31 years. Members are recruited from colleges around the country and each summer share a house and sing every day at locations all over the Island. At the end of July, Vineyard Sound performed its Midsummer Show at the Tabernacle in Oak Bluffs.

Singers typically stay with Vineyard Sound for one to three years.

Ryan Dirgins, a second year singer and business manager for the group, said that the revolving door of members offers the opportunity for a new sound each year, while a few returning singers ensure a lasting legacy.

“We’re carrying on traditions with the group from 1992,” Mr. Dirgins said. “Whether that is singing the same songs that they did that first year that they started or sharing the same jokes or sharing the same experience.”

The group performs publicly every day throughout the summer at Island churches and spontaneously on street corners. The Midsummer and Farewell concerts are longer and more thoroughly organized.

“We’re so excited to perform in the Old Whaling Church once again, Mr. Dirgins said about the Farewell show. “Not only is it the most beautifully resonant space, perfect for listening to a cappella, but it holds a lot of sentimental value for our group. It is the end of a summer’s long journey and a display of how much the group has improved since June 1... On August 19, we solidify the bonds that we created over the course of the summer with one final performance.”
