Last week, IU released a music video for Dear My Crazy Soulmate, the b-side to Unknown Planet (별로부터). Now, it’s time for the main course. Those hoping for a little more experimentation will appreciate this one, as the song forgoes Soulmate‘s gentle sound for a synth-powered instrumental that brings the drama.

I’ve always thought IU’s vocals work best set against either a symphonic or synth backdrop. Her tone tends to cut through these robust arrangements, offering a great anchor as ornate instrumentals swirl around her. In some ways, Unknown Planet recalls the more theatrical fare of her past, though it’s still pretty straightforward as a song. In fact, without the production backing it up I’m not sure Unknown Planet would have much appeal to me at all. Its melodies stretch out with a sense of grandeur but struggle to find a structure unique enough to draw attention on their own.

This is where Planet Unknown‘s instrumental comes in. I love the chugging synth that dominates the track. It makes everything around it feel more impactful than it is. The song’s final flourish is particularly galvanizing, as if we’re being lifted into space ready for some grand adventure. I’d love to hear IU develop this sound further with more compelling songwriting to match.

Grade: B-
