On paper, 'Bust a Groove' looks erratic: 148, 145, then suddenly 74. Anyone reading the metadata with a DJ's eye will spot the trick, though: 74 and 75 are exactly half of 148 and 150 — half-time readings, the kind BPM detectors produce when the kick breathes differently. Correct for that lens and the Lysergic Records compilation reveals itself: eight psy-trance cuts living almost entirely in the 145-156 range, with an internal architecture subtler than the spreadsheet suggests.
The start is direct: Joy Boy's 'Just a Party' opens at 148 and Aukan (IL)'s 'Jungle´s Medicine' eases to 145, two steps that set the pulse without burning ammunition. The first breather comes with The Concept Nemesis' 'Eternal Civilization', a nominal 74 that works on the floor as a change of texture rather than speed. 'Clair Obscur', the Ray Of Light and Uncle- M collaboration, is the longest piece here (8:11) and the most ambiguous in tempo (89 on the tag): a deliberate valley before the climb back.
The second half is where the record tightens. Only Human's 'Until Destiny' returns to 145 and is also the only cut in a minor key (F Minor), a dark shade right before the peak: Kontrax's 'Hackeado', 156 BPM, the fastest track and the shortest too (6:27) — pure peak-time economy. Flagrant's 'Soul Wave' drops the reading to 75 to decompress, and 'Motorica', a four-handed effort by SinusX and Dream Monsoon, closes at 146 with over eight minutes of runway: a long landing, not a hard stop.
As a sequence the pattern is clear: two pushes, one breather, repeat. Also striking is the insistence on Eb Major — opener, third cut and second-to-last share the key — a harmonic anchor that lends the set a coherence the tempo zigzag conceals. No remixes, no filler: eight originals that practically sequence themselves.
