PARTS is a two piece electronic duo based in Grand Rapids, MI that formed in December 2015. Members Alyssa Midcalf and Marley Ferguson alternate between lead and background vocals while forming a balance between light and airy, and dark and moody. The duo released their self-titled, three song EP in September 2016 which Gorilla vs. Bear described as "an ethereal collection of diaphanous, dreamily melancholy synth-pop".
