Joe has a low and cute voice, but can do surprising high notes without any problem. Since his joindate in late 2006, he has begun his "high notes travel" alongside Tom Cully, later joined by Liam Connery. He did the great "Salva" in the new version of Libera's Salva Me, adding a celestial atmosphere to the famous song. On the song "Never Be Alone" in their new album New Dawn (2008), Joe, together with Tom Cully, moved all the audience again with his high notes. Joseph also did the main solo for Stay with me in 2008.
