Developer takes the A-side, turning in the sort of roughed-up, rolling, perfectly functional 4/4 techno he's known for. "Observance" is long and moody, with eerily sagging horns extending over sprightly cymbals and gunshot-like chords. In contrast, "Brightly Dark" pushes more insistently, its modulated two-note riff leading the way, but it also feels a little less impressive.
Tolkachev's speedy cuts on the flip are pretty straightforward for him—less sharp-angled than his more abstract efforts—but intriguing nonetheless. "Raw 1," with its distinctively shrill lead and quick-humming undertones, is the record's blissful highlight. "Raw 2" has Tolkachev focused almost entirely on the bass and mids, and the result is a churning vortex of sound that'll likely turn legs into mush. It completes what's overall a nicely diverse four-tracker.
