Sister Says is sister and brother singer-songwriters Gillian and Robert Thomson. Inspired by a vintage sound caught up in a new-school world, Sister Says is not your typical singer-songwriter duo. The two perform their take on singer-songwriter soul throughout Canada and internationally. Songs are constructed and deconstructed, depending on their performance setting as they have shown up as a five piece and as a duo with percussion, keyboard and vocals or with electronic/live instrumentation .
