// note: Tempo changes preserved in elapsed time; displayed bars use the dominant tempo.
// note: metre changes (4/4 at bar 1, 2/4 at bar 4, 4/4 at bar 4, 12/8 at bar 6, ...) are rendered on a constant 12/8 grid of one bar per cycle
// note: duplicate parts dropped: ch 8 "Electric Guitar IV" distortion guitar (copy of ch 3 "Electric Guitar I" overdriven guitar, 0.083 beats late); ch 7 "Electric Guitar III" electric guitar jazz (copy of ch 4 "Electric Guitar II" electric guitar jazz)
// note: Full arrangement: all 70 bars on a 24-step grid, each part at one level. Source detail keeps the original performance.
