At 125 BPM in D minor, 'Firmament' doesn't rush; it applies pressure. The rhythm is tidy and forward-leaning, with a low end that keeps the room locked while the melodic haze drifts over the top. Energy pinned at ten, but it's controlled energy — the kind that comes from tension held rather than released.
I'd slot it in the deeper, later stretch of a set, after the room has settled and before anyone needs a lift. It builds atmosphere without fuss: warm, slightly melancholic, and patient enough to let the groove do the talking. The Innervisions restraint suits it.
