The three singers of Il Volo have made a kind of second home in the United States — and that certainly makes sense given the Italian group’s success here. After all, the U.S. was the first country they performed in after being discovered on an Italian singing competition show, “Ti Lascio Una Canzone,” in 2009.

The trio — tenors Piero Barone, Ignazio Boschetto and baritone Gianluca Ginoble — were teenagers at the time and looking toward global domination. The United States was stop No. 1. The group landed a guest spot on “American Idol,” a deal with Jimmy Iovine’s Geffen Records (a first for an Italian singing group) and a PBS special. A decade later, they are in the midst of a 10th Anniversary tour that stops Friday night at the Saroyan Theatre in downtown Fresno.
