Tarte à la myrtille

Acidcore is a hard, fast, and abrasive strain of acid-driven dance music that fuses the squelching TB‑303 lines of acid house/acid techno with the high-impact drums, distortion, and intensity of hardcore techno and early gabber. Typically running at 150–180 BPM, acidcore foregrounds relentless 909/808‑style kick drums (often distorted), off‑beat hats, clattering rides, and gritty percussion beneath hypnotic, resonant 303 sequences. The mood leans raw, underground, and rave‑oriented, with long-form arrangements designed for free parties and warehouse floors. Where classic acid emphasizes trippy groove, acidcore pushes the sonic aggression and tempo, preserving the hypnotic acidity while amplifying the energy for late‑night peak moments.

Psytrance (psychedelic trance) is a high-energy branch of trance music that emphasizes hypnotic repetition, richly modulated synth textures, and immersive sound design. Typically ranging from 138–150 BPM (with substyles slower or faster), it features a straight four-on-the-floor kick, a tight, rolling 1/16th-note bassline, and intricately layered FX—zaps, squelches, formant sweeps, and granular stutters—arranged to create a mind-bending, psychedelic journey. Tracks are commonly 6–9 minutes long, evolving through long-form tension and release. Harmony is sparse and modal (often minor, Phrygian, or Phrygian dominant), while rhythmic micro-variations, filter automation, and spatial motion (pans, dopplers, psychoacoustic tricks) carry the narrative.
