Why You Should Pay Attention: In the Nineties, Brandy was America's sweet-sounding R&B princess, confirmed by her turn as Cinderella in the Whitney Houston-produced remake of the classic story. She stole hearts and sold millions with her warm, dulcet voice on Number One singles like "Have You Ever?" and the Monica duet "The Boy Is Mine." Her pop presence in the new millennium hasn't been much (she hasn't had a Top 20 hit since 2002, though the Chris Brown-assisted "Put It Down" was an R&B smash) — but 2015 promises a new album, her first in three years. SXSW could be the kick-off of a comeback her fans have been waiting to witness.
