Nicoletta's “Les Acoustiques Gospel” tour blends her hits—“Il est mort le soleil”, “Mamy blue”, “Un Homme”, “Liberté mon Amour”—with Gospel and Negro Spiritual classics like “Oh happy day”, “Amazing Grace”, “Nobody knows”, “Joshua fit the battle of Jericho”. She also revisits Brel and Piaf repertoire, William Sheller’s hopeful songs, and “Summertime”, offering a powerful finale with Gounod’s “Ave Maria”. Ray Charles praised her unique voice, and Jean François Kahn lauds her as transcending between Mahalia Jackson, Edith Piaf, and Billie Holiday.
