The Martha’s Vineyard Chamber Music Society concludes its 38th summer season this Monday and Tuesday with an ambitious finale that includes a world premiere and the first-ever performance of a classic Stravinsky piece on the Island.

On August 11 at the Old Whaling Church and August 12 at the Chilmark Community Center, the trio of violinist Nancy Wu, clarinetist Anthony McGill and pianist Delores Stevens will perform the premiere of Then and Now and Forever, a piece commissioned by the chamber music society and written by the noted composer Morton Subotnik.

A Sunday matiné e musical puppet show for all ages at Che’s Lounge will feature musical monkeys who love to dance and play, with their friends Bella and Arakataka’s Little Band. Are You Looking for Bananas? is the name of this happy play about a musical land where musician monkeys live and enjoy life.

The play and its songs are written by Bella and they are performed live in both English and Portuguese by Bella and Carol Loud, a music teacher for children.

Sexton Brings Soul

American soul man Martin Sexton got his start playing on the streets and subways of Boston in the 1990s; Friday night he is playing at Outerland.

He released his seventh album, Seeds, last April on his label Kitchen Table Records. “I believe songs are seeds,” Mr. Sexton says about the collection, “once planted they can grow and nourish and inspire and with that, change the world.”
