Singers Heo Solji and Kim Song-yi brought 2NB to the K-Pop stage in 2006, captivating audiences with smooth, smouldering R&B, fiery crescendos and harmonies spun from gold. The duo parted ways after just two albums, but the group was revived in 2016 with new vocalists—Son Yoo-na and Kim Hyo-jin—and a fresh stream of lush, ardent pop. Recent hits like “Pink Pink” bring a jazzy, sun-drenched charm, and the acoustic guitar ballad “You Are The One” offers heart-wrenching tenderness. Even in collabs and solo ventures, both artists deliver soul-stirring laments with their sumptuous, soaring vocals.
