Since the Three Tenors first became superstars in the early '90s, a trio of tenors has become a standard vocal ensemble formation. The Tenors, however, expanded on that idea to form a quartet, comprised of Victor Micallef, Clifton Murray, Remigio Pereira, and Fraser Walters. The quartet's 2008 debut album quickly became a best-seller and was followed in 2009 by a holiday album, The Perfect Gift, which also went gold. In 2012 it released Lead With Your Heart, which featured the single "I Believe" and went on to win a JUNO award. All three albums are certified multi-platinum. The ensemble has performed all over North America and Europe, with some of the biggest names in both the popular and classical music arenas — from Sheryl Crow to Andrea Bocelli — and before numerous heads of state. Members of the quartet wrote eight new songs included on Under One Sky, the focus of their largest tour to that point, covering dozens of cities in North America during the 2015-2016 season.
