Formed after a two-year search, the quartet is comprised of American tenor David Miller, popular French singer Sébastien Izambard, Swiss tenor Urs Buhler, and Spanish baritone Carlos Marin. Their eponymous debut album was released in April of 2005 and featured a diverse playlist that included a cover of the Toni Braxton hit "Unbreak My Heart" and the Frank Sinatra standard "My Way," as well as "Nella Fantasia," a newly arranged -- with vocals -- version of "Gabriel's Oboe" from Ennio Morricone's score for The Mission. It became a massive worldwide hit, and the quartet returned in 2005 with Ancora, a ten-track collection of new music featuring the hit "I Believe in You" with Celine Dion. The similarly themed Siempre arrived in 2006, followed by Promise in 2008. The group's sixth studio album, 2011's Wicked Game, featured ten new tracks, including "Don't Cry for Me Argentina," "Come What May (Te Amore)," and a reworking of the Chris Isaak-penned title cut. They released their first Greatest Hits compilation in 2012 and embarked on a European and North America tour. In 2013, they issued the show tunes-centric A Musical Affair. After touring the new material, and taking a little time to rest, they returned to the studio in 2015 to record their seventh album, Amor & Pasión, focusing on a Spanish theme this time around. They subsequently set out on a world tour in support. ~ James Christopher Monger
