Well, I do not really know if somebody maybe posted a thread about her, however, she's Elisa, an italian songwriter.
Although she's Italian, she records mainly in English since her first record in Italy, Pipes & Flowers, but her first debut in America was in 2008 because her song, called 'Dancing', it was used in one of the seasons of So You Think You Can Dance.

Anyways, this year she has come back in the U.S.A with a new album, Steppin' on Water, but it has been a flop due to bad promotion! .-.
