I really like Il Volo. The boys have a great sound for such young voices, and they have good arrangers and producers providing them with well-written material that’s also recorded well.
Good stuff. One niggly lil thing though: they all have a strong tendency to take Italian vowel production into all the languages they sing in. Oh, it’s not offensive, but it is pretty glaring at times. Take “Stille Nacht” (below). Beautifully sung, but… the vowels are often not German. Oh, well. Picky, picky, picky. 😉
