The audience of The Old Lynn Concerts are a seasoned group with high expectations. Some might even say that they are spoiled, as over the past 13 years, many top-flight performers have been presented in the small, rural church tucked away in the northeastern corner of Pennsylvania. Last night, Mara Levine and her musical friends raised the bar yet again.  Levine's gift for harmony and her powerful stage presence breathed new life into old songs and made instant favorites of the new.  Engaging the audience from the outset, Mara Levine literally left her audience on a high note as she subtly converted them all to members of her own 120 person choir.  Levine's concert was a highlight of the season.  Lorne Clarke
