Unrecognizable is Sinead O'Coonor, the famous Irish vocalist who was Number in the 90s with the Prince song "Nothing Compares 2 U". In the image we see her at a concert in her country, at the Bray Seaside Festival, where she performed with musician Natty Wailer, from Bob Marley's The Wailers group.
And in this video, we see her singing a new song that will be included in her next album. 'Home': It was at a concert in St.Petersburg in June of this year.
