Composer SIR Andrew Lloyd Webber is giving an unknown teenager her big break after she stunned guests at his annual arts festival. Ambitious ANDREA ROSS was just 13 when she sent Lloyd Webber a demo of her singing via the Internet. The composer then booked her for his Sydmonton Arts Festival in England. Two years later, he has produced the teen's debut album, MOON RIVER. He says, "I first heard Andrea singing when she sent me her music via the internet. She was just 13 and I immediately invited her to perform at my arts festival, where she delighted the audience. "Andrea is still only 15 and it is going to be great to see her develop, as she has enormous potential to become a very big artist." Ross' first album will be released next month (MAR07).
