Marble rolls in at a steady 125 BPM, riding a hypnotic grid that feels far more supple than its energy 9 rating suggests. Bärtaub lets the groove breathe in key 9B, threading warm, tactile frequencies through a framework that is ruthlessly economic yet never sterile; every hi-hat flicker and sub-bass swell is placed with the confidence of a selector who understands that restraint hits harder than force.
In the room, this is a 3 AM weapon: compact enough to slip between moodier deep-tech passages, yet possessed of that distinctive R&S-backed forward motion that keeps bodies locked. It builds no grand crescendo, choosing instead to carve out a single, unbroken spell of late-night hypnosis. For the leftfield underground, that specificity is its power.
