Union Chapel in Oak Bluffs brings composer, organist and music director Mark Miller to play on its newly restored organ for a free concert on Friday, July 28 at 7:30 p.m. The concert is the first in Union Chapel’s two-concert series this summer. The second recital takes place August 28 and features musician Alcee Chriss.

Mr. Miller’s concert will feature works by Bach and Undine Smith Moore, and some of Mr. Miller’s own compositions, including his recently-composed song cycle, Dream Variations: Songs on the Poetry of Langston Hughes.

“He’ll also lead the audience in singing some of his own songs. I know people will love that,” said Bill Peek, Union Chapel music director. “It’s great stuff, and it’s very empowering and beautiful music.”

Mr. Miller is a professor of church music and composer in residence at Drew Theological School in Madison, N.J. and a lecturer in sacred music at Yale University’s Institute of Sacred Music. When he is not teaching, he is minister of music at Christ Church in Summit, N.J.

Having spent his summers on the Vineyard as a child, Mr. Miller now settles in for a few weeks each July and August as choir director for the First Congregational Church of West Tisbury.

“Mark is a brilliant musician, and he’s a very charismatic musician as well,” Mr. Peek said.
