From the start of “Supersonic,” it’s apparent that Sidewave is delivering music that is both thought-provoking and emotional. At first listen, it sounds like it might be going the way of a good old-fashioned emo song, a quintessential single of the early 2000s. Instead your ears are met with airy vocals, pulsating chords, and ethereal synths. The track doesn’t necessarily match up with the emotions it evokes, but there’s a magical element that holds your attention and makes you curious for more.
