Breaking away from their contemporaries, South Korean girl group elevate their inspired blend of dance genres and R&B to new heights on their second EP, . U.K. garage, drum'n'bass, and Jersey and Baltimore club fill the front half of the effort, a thrilling triple hit of "New Jeans," "Super Shy," and "ETA." Things smooth out on the back end with the lush, seductive "Cool with You," "Get Up," and "ASAP." are so adept at all styles that the shift feels effortless and fresh, positioning them at the fore of the next wave of K-pop daring. ~ Neil Z.
