Track 4: Ghost Protocol — progressive house, dark to euphoric
F minor → Ab major, 128 BPM. deadmau5-style structure: - Intro: kick + filtered supersaw pad - Build 1: saw bass, hypnotic 16th note lead, offbeat hats - Breakdown: kick drops, melodic lead, noise riser - Drop 1: dark and driving, pluck stabs, full energy - Breakdown 2: emotional turn from minor to major - Drop 2: euphoric Ab major, everything opens - Outro: filtering down, kick rides out, dissolves Co-Authored-By: Claude Opus 4.6 (1M context) <noreply@anthropic.com>
