FUSE TV - Red Velvet Returns With Dreamy R&B Ballad 'One of These Nights': Watch

As fans know, Red Velvet's group name represents more than just a delicious dessert flavor, but its musical sensibilities. The "Red" part of the girl group's name reps their bold and quirky side (heard in past singles like "Dumb Dumb" and "Ice Cream Cake"), while the "Velvet" speaks to their sensual, R&B-leaning tendencies (like in "Automatic" and "Be Natural"). After going super-quirky with their debut full-length LP The Red late last year, the girls are going more velvety than ever with their new EP, The Velvet.

New single "One of These Nights" begins as a standard ballad, opening with strings and piano, before evolving into a sweeping, orchestral arrangement. The girls flip the sound on its head at the 1:40 mark when a trap beat kicks in to give the strings a modern flavor. Musically, it's a remarkably bold move for the group, at a time when every K-pop act is looking to score its boldest, catchiest dance hit.
