With their big voices, fresh sound and fun attitude, MAMAMOO shake up the usual expectations of a K-pop girl group. The four-piece's songs draw from pop's soulful side: funk, jazz and hip-hop are all thrown into the mix, along with a healthy dose of humour and sass in their lyrics. But their main musical element is confidence, and when it's time to get serious, whether on a sultry R&B slow jam or a tender ballad, they deliver with full-throated emotion.
