I just thought I´d like to tell you about an amazing female artist, whose music I stumbled upon a few days ago, Catya Maré, a classical crossover violinist and songwriter.
Her music creates goosebumps, as Hayley´s does...
Her official website is http://www.catyamare.com
and her three albums are available from every major digital music store. I guess you might enjoy her songs a lot.
