PORTLAND — On May 17-18, Women in Harmony will present On the Road, a concert of choral music in celebration of journeys both geographical and personal. A central message of Women in Harmony’s mission is communicated in the text of Never Turning Back: “we’re gonna keep on walking forward, keep on singing proudly, work for change together, never turning back.”

The concert will also feature three movements from (flight): a borderlands song cycle by Maine composer Erica Quin-Easter, a work addressing issues of migration and immigration which was premiered by Women in Harmony in 2011. Randall Thompson’s Come In is a setting of a Robert Frost poem about a wanderer in the woods. Journeys of the spirit are the subject of Swimming to the Other Side, Swing Low, and Welcome the Stranger.

Performances will take place at Woodfords Congregational Church, 202 Woodford Street, at 7 p.m. Saturday, May 17, and at 4 p.m. Sunday, May 18. Tickets are available in advance ($12) at Longfellow Books, Starbird Music in Portland, and Nonesuch Books in South Portland or via Women in Harmony’s website, www.wihmaine.org. General admission is $15 at the door.
