Over-Under is essentially two mini-EPs—one to each side—showcasing two distinct strands of the Montreal producer's sound. The A-side best explains why Jaar came calling: fashioned from rich acoustic instrumentation and delicate beats, these three tracks exude a sort of hi-def aimlessness that makes them very pleasant coffee-table fare. "1" sees harps and meandering, wordless vocals lead the way, while the briefer, piano-led "Ostinate" could almost have been culled from an ECM recording. "ADSR Toms," centred on the titular pitched tom-toms, is a tad more synthetic. All three slip dreamily by without making much of an impression, but in the time-honoured easy listening tradition, that's probably the intention.
Over on the B-side the basic materials are the same, but their deployment is grottier and a touch more geared towards the dance floor. It's a small difference but a significant one. "Refraction" is a lilting delight, but "C Trigger" is particularly striking. Don't let the feather-lightness of its chords fool you—there's a pretty chunky slow-techno throb under there, which generates a pleasing tension. Rounding off the EP, "Metroplex Theme" remains Gragg's finest hour, but there's plenty here to suggest that his best is yet to come.
