At age 15, Lee turned down an offer from Sony Hong Kong to join the short-lived girl group Ris-K.

Eager to explore her Chinese roots and to see the world, in 2002, Lee joined another group called NRG performing in Hong Kong.

Lee aligned with Vancouver-based Hipjoint Production, and achieved "indy-cred" with her debut album What a Difference a Day Makes.

Initially, her music drew attention in clubs across Canada; radio soon followed with her first single "The Naughty Song", nominated for a Juno Award.

Featuring production from multi-platinum and three-time Juno Award winner Perry Alexander (Keshia Chante, Shawn Desman) and KUYA (Nelly, Ginuwine, MASE), Sinful Innocence enthusiastically explores society's "good girl/bad girl" double standard from Lee's own independent liberal perspective.

Later, in November 2011, a remix of “Best Shot” was released, with a second song, “Fashion Show.” An accompanying music video was posted to YouTube from her official account.
