The Old Sloop presents a concert May 20 featuring mesmerizing Welsh performer Martyn Joseph with award-winning singer-songwriter Antje Duvekot opening the show. The performance will be in the handicap-accessible sanctuary of the First Congregational Church of Rockport, 12 School St. at 7:30pm.

Martyn Joseph is a completely unique and mind-blowing artist. Take everything you think you know about singer songwriters….and rip it up. For one man and a guitar he creates a performance with a huge far-reaching sound that is energetic, compelling, and passionate. Be it to one hundred people or twenty thousand, he blows the crowd away night after night. Concerned with making music that is relevant and vital to his audience, he engages with challenging narratives tackling the complexity of the human condition, underpinned with a promise of hope.

Opener Antje Duvekot is the winner of some of the world’s top songwriting awards, including the Grand Prize in the John Lennon Songwriting Competition, the prestigious, Kerrville (TX) Best New Folk Award, and the Boston Music Award for Outstanding Folk Act.
