"There will be a great variety of music and performers from the united states and abroad," said Kevin Birch, executive director of St. John's Organ Society.
The summer concerts started to share the church's historic organ with the community.
This children's choir is a tradition in the Bangor area. They have been performing here for more than 30 years. Thursday marks the third year they're performing at St. John Church.
"We do a tour in America every two years and we have a nice welcome. And our kids can discover what is really American people and the values of generosity, of hospitality," said Francis Bardot, a professor in France.
The children traveled all the way from France to perform right here in Bangor.
The choir trains many hours a week with a conductor and performs their talent throughout France as well as places abroad.
"They can discover young french people singing very difficult, very difficult music, beautiful french music," Bardot said.
The executive director of St. John's Organ Society said it's a great opportunity for everyone.
The conductor said they're very excited to be performing in the northeast tour and they want the audience to join in.
"We will end the concert with American songs and I ask the people to sing with us so it's only to say thank you," Bardot said.
