The band consists of Megan James on vocals and Corin Roddick (instrumentals); both grew up in Edmonton, Alberta. James uses written work, which she originally did not intend to release to the public, for many of the band's lyrics. During live shows, Roddick uses a custom-built, tree-shaped instrument to drive both live sound and lighting. During live appearances both wear clothes custom designed and sewn by James. The duo were originally members of the band Born Gold (previously called Gobble Gobble). While on tour with Gobble Gobble, Roddick began experimenting with electronic production and beat-making. James was asked to sing on a track called "Ungirthed," which led to the formation Purity Ring. The song was released in January 2011. On April 3, 2012, Purity Ring was signed by media company 4AD worldwide and Last Gang Records in Canada. Later the same month the band announced their debut album, Shrines, which was subsequently released on July 24, 2012.
