After the 2006 dissolution of Destiny's Child, Kelly Rowland underwent a solo reinvention that saw the versatile urban singer riding bhangra beats and singing R&B torch songs. Since then, she's explored wubbing techno-pop, harmonized over 808s and airhorns and chirped hooks on downtempo slow-burners. But Rowland's charisma also flourishes when she's a foil: she's an exacting lover for Lil Wayne on the electro-hop slow jam “Motivation”, and her soulful belting lifts David Guetta's house floor-filler “When Love Takes Over” to the heavens.
