Gemini Club is made up of a few guys from Chicago who deliver dancey synthpop to the kids. “By Surprise” definitely fits that definition; it also happens to be, coincidentally, a little… surprising. Ok, ok, it’s definitely straight-forward pop music, no doubt. But the jazzy chords that follow the first chorus — didn’t see those coming. Plus, the tempo is just about perfect for a workout mix. You can thank me later, when you’re shamelessly dancing on the elliptical machine at the gym. Work it. Own it.
