Vox Nova Chamber Choir is marking the Winter Solstice with a pair of concerts.

The group will first perform at 7:30 p.m. Saturday, Jan. 20, at the Franco Center, located at 46 Cedar St. in Lewiston; the second performance will take place at 3 p.m. Sunday, Jan. 21, at Studzinski Recital Hall at Bowdoin College in Brunswick.

The music for Winter Solstice heavily evokes both the wildness of nature and the cultivated aspects of the season. Stephen Paulus’ “Evensong” and “Auld Lang Syne” are seasonal while other pieces highlight the extreme beauty of northern landscapes. Erik Esenvalds’s “Northern Lights,” Ola Gjeilo’s “Tundra,” “Winter Light” for chorus and string quartet by Michael Gandolf, and John Muehleisen’s “Winter Light” create a vivid, wintry landscape for the audience.

Featured instrumental performers include Virginia Flanagan (harp), Sam Schuth (violin), Tracey Jasas-Hardel (violin), Evan Cuddy (viola), Shannon Allen (cello), Steven Weston (flute), Amy Maier (piano) and Peter Stuart (trumpet).

Vox Nova Chamber Choir, which was established in 2009, under the direction of Shannon Chase, champions the expansive body of modern and contemporary choral repertory. The Chamber Choir is comprised of 32 adult singers and Intima is a small group of 13 singers from within Vox Nova Chamber Choir.
