It doesn’t take long to fall for Lightning Love. Four coos and a jaunty keyboard line, and Leah Diehl’s got you swooning. “Together” is a charming introduction to the Ypsilanti, Mich., trio, but more treats lie ahead on Blonde Album (Quite Scientific), their second full-length: angelic harmonies, synth waltzes, good-faith promises and flirty drums courtesy of Diehl’s brother Aaron. All that sweetness makes you root for Diehl whenever she figures out what she wants, whether that’s turning a pal into something more (“Just Friends”) or finding their way back to platonic status (“Awkward”). “Bobby Thompson” raises the stakes of the typical twee-pop boy-girl sparring by erupting into an all-out rocker, but Lightning Love always stays true to the frilly heart beating within.
