Rain didn’t stop the pitch perfect a cappella group “Hyannis Sound” from captivating a full house at the church last night. They’re just college guys who like to sing, and performing is their summer job. They’re around for another 10 days or so, back at the church next Monday at 7pm, and at the Falmouth Jewish Congregation this Wednesday. They’re optimistic and exuberant, and the small personal stories they share are endearing. The musicianship is outstanding. Go if you can!
