New Zealand’s Annabel Alpers conjures a cross-genre symphony on her second album as Bachelorette. Starting out at a humble folk gait, “Instructions for Insomniacs” soon floods the mix with ambitious electro-pop lushness, while “The National Grid” bolsters Alpers with a robust choir of her own multiplied vocals. Both the brainy lyrics—often delving into scientific themes—and brain-busting layering across My Electric Family can recall Stereolab, but Alpers’ vividly rendered juggling act exudes a psychedelic sophistication that’s all her own.
