SHARING THE BILL: Mara Levine, left, and the folk-rock trio Gathering Time, collaborate at a concert on May 19 at Christ Congregation Church.

Mara Levine and Gathering Time will perform an evening of socially conscious folk song and harmony arrangements on Friday, May 19 at 8 p.m. at Christ Congregation Church, 50 Walnut Lane. The concert is presented by the Princeton Folk Music Society.

The performance is almost a double feature, because Levine and Gathering Time have independent acts. But they frequently collaborate. Gathering Time supports Levine on her sets, reproducing the intricate harmony arrangements of her recordings in detail, and also presenting their own vocal harmonies, guitar playing, and percussion.

Levine has been creating interpretations of traditional and contemporary folk songs for many years. Her voice is said to be reminiscent of her inspirations, Judy Collins and Joan Baez.

For over a decade, Gathering Time (Stuart Markus, Christine Sweeney, and Gerry McKeveny) has toured both in the U.S. and internationally, mixing new interpretations of traditional tunes with their original songs. Gathering Time evinces deep roots in ’60s folk-rock, with a dash of traditional folk in the mix. Their sound reflects the voicings and arrangements of performers such as The Byrds, Peter, Paul & Mary, and Crosby, Stills & Nash, brought into today with an acoustic-electric alchemy all their own.

Tickets are $5-$25. Visit princetongfolk.org. Masks are required.
