Empire of the Sun are no strangers to life-affirming anthems, but behind the pyrotechnics lies a subtler side. With “Concert Pitch”, they take a soft swipe at The Cars' streamlined New Wave, while “Delta Bay” puts woozy falsetto in the service of jangly ‘60s psych. Quieter still, the shimmering “There's No Need” is the vocoder-soaked slow jam to satisfy every listener's inner prom king or queen.
