Whether exploring old school pomp or zippy electro-pop, this K-pop quartet tap an exuberant, fast-moving current. They made their name by taking a ‘60s girl group sound—loaded with horns, handclaps, and harmonies—and speeding it up to a modern-day tempo. More recently, the band has applied this same strategy to fizzy electronic pop, crafting heart-racing numbers that prove impossible to resist. Few do high-energy K-pop as well as Dalshabet.
