GQ is an a cappella and barbershop vocal quartet from Baltimore, MD, composed of four great friends: Amanda Sandroni, Katie Gillis, Ali Hauger, and Samantha Tramack. They sing a variety of styles, spanning different genres and decades, and have a serious passion for creating a unique sound!

They’ve come a long way since they were the 2013 Rising Star Champions: they’ve placed as high as 3rd (2019) while collecting medals in the Sweet Adelines International competition. In 2026, GQ became the first women’s quartet to win the Barbershop Harmony Society International Competition in St. Louis.
