Before landing in the mainstream, Cantopop singer Kay Tse was an indie darling drawing inspiration from social issues to make her brand of contemplative pop numbers. "Wedding Card Street", with its clever interpolation of reflective lyrics and aching piano-driven melodies, tugged at heartstrings with a nostalgia-charged message. Subsequent releases brought even more chart-friendly material, and as the beats grew bigger, so did the perceptive songwriting. That perfect blend of commercial savvy and artistic independence is the reason Tse is one of Hong Kong's most prolific pop voices.
