This Spring the Carriage Barn Arts Center, home to the New Canaan Society for the Arts will host its 27th annual Spectrum Contemporary Art Show. Spectrum is a juried exhibition of original, contemporary artwork by local and regional artists, and invites submissions in all media. All entries must have been created within the past two years and not have been previously exhibited at the Carriage Barn. Guest Juror and contemporary art specialist Adrienne Ruger Conzelman, of ARC Fine Art, selected works rendered in grayscale — black and white and anything in between.
