At home she would listen to soul and R&B tunes, and while singing along she discovered the strength of her own voice. She found inspiration in soul legends such as Mary J. Blige, Stevie Wonder, Brandy Norwood, and her greatest idol, Italian R&B diva Giorgia. Later, she started to attend karaoke competitions, most of which she was able to win effortlessly.

Claudia D'Addio becomes Diamá

Since, more than once, presenters introduced her as Claudio D'Addio, which is the male form of Claudia and since many others mispronounced her name, she and her management decided to use an artist name for her debut album. Diamá was chosen because it contains the last three letters of her own name Clau(dia) and the first two letter of (Ma)urizio, an homage to her best friend, who died in a tragic accident in September 2009.


Diamá is currently working on her second album.
