Marianni is one of the most popular Brazilian vocalists on the scene today, with her silky, sensual voice, and winsome personality that charms audiences wherever she performs, whether with one of her own ensembles, or as vocalist with another band — for example, at Austin Carnaval with Beleza Brazil carnaval band. Her repertoire ranges from Brazilian bossa nova favorites, samba and MPB (Brazilian popular music) to American favorites and some of her own compositions.
