The epochal arias that dominate In Cold Blood are synth-pop and 21st-century electronica. White Sea (a.k.a. singer/songwriter Morgan Kibby) takes a richly melodic approach to her tales of heartache and desire, whether she’s embracing martyrdom (“Small December”) or claiming superhuman powers (“Warsaw”). Tracks like “They Don’t Know” and “NYC Loves You” attain a cinematic grandeur, balanced by the day-glo funk of “Prague” and the feverish pulsations of “Flash.” It adds up to a sonic tour de force that never stints on passion.
