Ken Tucker

The Australian songwriter who has written hits for Rihanna, Beyonce and Katy Perry just released an album of her own. Critic Ken Tucker likes Sia's singing, in part, because of its imperfections.

The Texas-raised singer connects to R&B music from the past — and challenges himself to give it an updated sound — in his new album. Critic Ken Tucker says Bridges' album packs an emotional punch.

The California quartet, led by lead vocalist and main songwriter Taylor Goldsmith, has a new album called "All Your Favorite Bands." It explores sadness and doubt without being downbeat.
