The next great British female vocalist? Holly Lapsley Fletcher makes a robust play for the crown with a startlingly poised debut album. Weaving ice-cool electronic production into her high-end torch songs, it’s still that rich, doleful croon that might just hand the 19-year-old a place at pop’s top table. “Hurt Me,” “Love Is Blind,” and “Silverlake” are your starting points: evocative and possessing giant, rousing choruses to thaw the iciest of dispositions.
