Kelly Sweet was never a contestant on a TV singing competition, and she isn't the product of the latest svengali producer. Which, in 2007, makes her something of a rare new pop star. Her approach to the genre is pretty unexpected, too: Temperamentally, the flame-haired chanteuse falls somewhere between Celine Dion and Sarah McLachlan, which is to say she's all softness, warmth, and sincerity. Vocally, she's a ringer for Amy Lee of the rock band Evanescence, minus the goth fixation. And categorically, her closest fit within the wide world of pop is classical crossover. Consider her the female Josh Groban then, with the multilingual skills to match: In addition to a haunting and miraculously un-awful rendition of Aerosmith's "Dream On," she busts out a French track, "Je T'aime," that sends out summery flutters; a Sanskrit song from the film "Gladiator," "Now We Are Free," that impresses with its depth of feeling; and an Italian number, "Giorno Dopo Giorno," that ripples with tenderness and sentimentality. Sweet is a songbird with a wide wingspan; her debut mostly soars. --Tammy La Gorce
