For better or worse, Brave Girls have always been a delivery method for songs by their agency head, Brave Brothers. This obviously limits their sound somewhat, but for fans of the Brave Brothers style, they’re pretty much the gift that just keeps on giving. And now that bigger groups like AOA and Sistar have (mostly) moved on to different producers, Brave Girls’ music is the best kind of k-pop throwback.

New single Rollin’ hits a middle ground between the sensuous Deepened and raucous High Heels, both from last year. In doing so, it offers one of the girls’ most limber tracks yet. The instrumental pulls from the popular tropical house trend, but rather than simply throw in a repetitive riff here and there, the entire track is built on this sunny synth sound. Thankfully, the production smooths out any elements that might become derivative, tying every element together into a cohesive whole. It’s a classic, propulsive dance sound that should age quite well.

Similarly, Rollin‘s melody doesn’t reach for any tricks or trends. Its verses float by without leaving much of a mark, contributing to the general vibe rather than drawing attention to themselves. The song’s strongest moment is its dynamic chorus, which covers the gamut from breathy lower register to full-on rave. Brave Girls’ voices can sometimes come across a bit sharp depending on the way they’re produced, but that characteristic actually enhances Rollin‘s chorus, bringing a sense of urgency to its climactic second half. It’s yet another display of Brave Brothers’ songcraft mastery at work.
