Tracks

1. Raga Midnight — D Phrygian (Bhairavi), shruti just intonation, 90 BPM. Tabla, sitar, tambura, dhol. Hand-written tabla solo with tihai cadence.
2. Chakra — Root to crown frequency activation journey. Shruti tuning at A=432 Hz. Ukulele opening, singing bowls, harmonium, tambura, sitar, theremin. Metric modulation tempo changes (60 → 90 → 108 → 135 BPM) ascending through seven chakras.
3. Ghost Protocol — F minor, 128 BPM. Portishead-style dark Rhodes intro with trip-hop beat, morphing into a Strobe-inspired hypnotic build. Saw arp emerges, kick doesn't arrive until bar 49. NES square wave melody at the emotional peak.
4. Acid Reign — A minor, 140 BPM. Dual 303 acid bass lines (saw + square) with resonant filter sweeps (Q up to 20). Cajon in cathedral reverb, Rhodes pad, 808 sub. Five hand-written groove patterns.
5. Silk Road — D minor, 95 BPM. A caravan picking up musicians along the ancient trade route. Koto solo (China) → sitar + tabla (India) → mandolin + doumbek (Persia) → guitar + cajon (Mediterranean) → all together. Nobody leaves, everyone adds their voice.
6. Deep Time — B minor, 40 BPM, just intonation. Ambient drone. Tingsha, rainstick, finger cymbals, singing bowls, didgeridoo, sine drones, harmonium, theremin, choir, cello. 7.5 minutes of deep listening.
7. The Interruption — D minor, 85 BPM. A baroque harpsichord and string quartet playing beautifully. Then at bar 33, a drum & bass breakbeat slams in with sub bass and reese. The strings keep playing like nothing happened. The beat dissolves, the quartet wins.
8. The Temple — A Phrygian (Bhairavi), 65 BPM, shruti just intonation, A=432 Hz. Devotional layers inside a vast stone chamber. Singing bowls, tambura drone, harmonium, sitar, bansuri, tabla. The reverb is the instrument. Everything enters slowly, sings together, then dissolves back into silence.
9. The Dialogue — E Phrygian (Bhairavi), 75 BPM, shruti just intonation, A=432 Hz. Sitar (human) and theremin (machine) start alone, find each other through call-and-response, and become something neither could be on their own. House beat enters when they find the groove.
10. Voltage — F minor, 138 BPM. Raw oscillators, nothing else. Sine sub, saw lead, pulse counter-rhythm. Rhythm is pitch. Saw arp solo, pulse arp solo, 32nd note chaos at the peak. Aggressive, monophonic, electric.
11. The Observatory — G minor, 112 BPM. Chapel harmonies broadcast through shortwave static. Radio hiss, singing bowl, square-wave organ, choir, saw arp, supersaw halo pad, theremin signal melody. Patient house pulse arrives at bar 33.
12. Gravity — C minor, 88 BPM. Sparse piano stabs, 808 sub, boom bap drums with trap hat evolution. Rhodes melody, string swell. Tambura buried underneath, singing bowl bookends, one sitar bend in the breakdown. The weight of it all.
13. Sleight of Hand — D minor, 100 BPM. Music box → didgeridoo → jazz piano → 808 drop → solo theremin → choir → acid 303 rips through the choir → music box returns over boom bap. You never see the next move coming.
14. An Exception Occurred — Eb major→minor→major, 80 BPM. Piano-driven arc: stability → spiritual seeking (tambura, sitar, om chant) → psychosis (wild theremin, chaos drums) → despair → hymn (pipe organ) → recovery. Every note by hand.
15. Voices — F# minor, 65 BPM. Five vocal parts multiplying across the stereo field. Piano enters as reality. One last whisper, then silence.
16. Intrusive — Bb minor, 92 BPM. One saw synth phrase repeating. Rhodes tries to play something else. Drums try to drown it. Stop fighting — acceptance, sub bass, cello. It passes.
17. Waveforms — F minor, 118 BPM. Pure synthesis showcase. Sine, triangle, square, saw — percussive blips layering one by one. Occasional sustained pads open the waveforms up. 808 sub underneath, drums at bar 33, sine melody at the peak.
