MATRIX BLEND
================================================================

Blend by Ryan Shubert
April 2026

Mixed in Reaper 7 at 24-bit / 44.1 kHz.

The two sources were loudness-matched and sample-aligned per
song. The blend is approximately 60/40 SBD-dominant across
the musical range, with the sub-bass being 100% SBD and the
high-end leaning SBD as well.

Processing was deliberately light and transparent:

- Light corrective EQ on each source (linear-phase, iZotope
  Ozone 12). The SBD got a small subsonic cut and a gentle
  presence-range trim; the AUD got a high-pass to clear
  room rumble, a low-pass to tame the HF cliff, and a few
  small bell cuts in the low-mids and presence.
- A very light master EQ (sub-1 dB moves) and a true-peak
  safety limiter set at -1.0 dBTP (touching peaks only —
  no loudness processing).
- No compression, no saturation, no dynamic EQ, no reverb,
  no stereo widening, no time stretching or pitch correction.


================================================================
NOTES
================================================================

- Set 2 is seamless (as in the original Miller SBD).

- The Miller SBD already contained a small AUD patch in Drums
  from 2:05 - 3:02 (source: etree supplies). This patch is
  retained in the matrix and blended with the Clugston AUD at
  the same point.

- Two brief audience source dropouts occur during Sugaree
  (d2t03). In the matrix, the SBD continues uninterrupted at
  these points, so the dropouts are not audible in the final
  blend. Noted here for documentation.

- Track boundaries were set independently for this matrix and
  do not match either parent source exactly.

This is my first matrix attempt, and to the
best of my knowledge no prior matrix of this show has been
publicly circulated on etree, Lossless Legs, or the Internet
Archive. Huge thanks to the tapers who braved the crowds and
the weather to capture these shows in the first place, to the
transferers and masterers who have carefully preserved and
remastered these recordings over the decades, and to the
Lossless Legs community for keeping this music alive
and freely accessible. None of this exists without all of
you. Any flaws in this blend are mine; all the beauty
underneath it is theirs.
