Hong Kong singer/songwriter Gloria Tang Tsz-kei doesn't call herself G.E.M. (“Get Everybody Moving”) for nothing. Gifted with unusual power and range, she has been authoritatively belting out energetic dance pop and poignant ballads since her 2008 debut. While a reality-show role featuring robust covers of hits by Mavis Fan and Jay Chou eventually made her a household name, show-stopping originals like "Someday I'll Fly" and "Bubble" prove she's a true artist.
