Brent Mydland

1. Golden Age

   1975–1979

   Instrument

   Hammond B3 organ + Leslie speaker cabinet (the rotating-horn doppler sound); Fender Rhodes Mark I (with 'bell' tone hot in the mix); analog synths (Minimoog, Prophet-5) appearing as the rig builds out

   Signal

   B3 → Leslie (mic'd on the rotating horn); Rhodes → DI + keys amp; Minimoog/Prophet → keyboard mixer → PA

   Defining

   The first 8 months of Brent — joining mid-tour 1979 with Keith just having left — is Brent reading material on the fly. His Hammond playing leans more bluesy and less jazz-leaning than Keith's piano had been; the band's harmonic palette pivots hard. The Rhodes is the piano voice early — bright, bell-like, very different from Keith's tour grand.

   Dial in

   B3 clone (modern Hammond XK, SK, or Nord C2) → physical or modeled Leslie. Drawbar setting: 88 8800 000 (top three drawbars only) for the classic 'jazz organ' setup. For the Rhodes voice, push the bell-tone (a brightness/mid-EQ on most modern Rhodes models) and use chorus heavily.

2. Brent era

   1980–1984

   Instrument

   Hammond B3 + Leslies constant; Fender Rhodes Mark I primary through 1981; Yamaha CP-70 electric grand in 1982 only; Yamaha GS-1 FM synth replaces analog rig + electric piano in 1983 (with Minimoog + Prophet-5 transitioning out)

   Signal

   B3 → Leslie; Rhodes/CP-70 → DI; GS-1 → DI + monitor send

   Defining

   The Brent era proper. His original songs enter rotation (Far From Me debuts 3/30/80, Easy to Love You had debuted 8/14/79, etc.) and the B3 + Leslie sound is the harmonic core of the band's slower numbers. The GS-1 (1983 onward) brings glassy FM-synth piano + brass voices into the rig, the first big shift toward digital sound.

   Dial in

   B3 with drawbars 88 88 000 + chorale Leslie on slower passages; 80 0000 008 (mid drawbar pulled) for bluesy turnarounds. For Brent's solo passages, start single-note (right hand) and build into chord-stab octaves. Any FM-synth VST will get you in the GS-1 neighborhood — go for 'electric piano' and 'brass section' patches.

3. Late 80s

   1985–1989

   Instrument

   Hammond B3 + Leslies still central; mid-80s adds E-mu Emulator II (the band's first true sampler); 1987 rebuild (under Bob Bralove): Kurzweil MIDIboard controller → 2x Roland MKS-20 piano modules + Kurzweil 250RMX sampler rack + Roland S550 sampler + Oberheim Matrix 1000 synth + Lexicon PCM41/PCM70 effects + Akai MPX820 mixer

   Signal

   B3 → Leslie 122; MIDI controller → rack of sound modules → Lexicon effects → keyboard mixer → stage mix

   Defining

   Brent's most expansive period — Bob Bralove rebuilds the keyboard rig around MIDI in 1987, integrating the Kurzweil 250RMX (rack version of the famous K250 sampler) for orchestral/string patches. 'Touch of Grey' has Roland piano + B3 layered on the choruses. Brent's vocal range expands to a tenor lead voice on his original material, where he's now writing as much as Garcia-Hunter on some shows.

   Dial in

   B3 clone for the core sound (drawbars 88 8000 000 for ballads), MIDI controller into a sampler with 'orchestral strings' or 'choir' patch layered underneath at ~30% volume. The Roland MKS-20 piano voice is essentially a high-quality sampled grand — any modern grand-piano VST gets you close.

4. Final

   1990–1995

   Instrument

   Same late-80s Bralove rig — B3 + Leslies, Kurzweil controller, Roland MKS-20 piano modules, Kurzweil 250RMX, Oberheim Matrix 1000, Lexicon effects rack

   Signal

   Same routing as late-80s; no significant 1990 changes — Brent's setup was stable for his last year

   Defining

   Brent's last shows. His playing in spring/summer 1990 was strong — the 3/29/90 Nassau run is widely cited as his peak. 7/23/90 Tinley Park is his final show; he died of accidental overdose three days later, 7/26/90.

   Dial in

   Same as late-80s rig. If you're chasing the final Brent sound, focus on the spaces — his playing in 1990 leans toward sustain and vocal-style phrasing rather than chord stabs.

   Listen

   3/29/90 Nassau Coliseum · 6/24/90 Sandstone (Foxboro) · 7/23/90 Tinley Park (last show)

SourcingBrent's tenure: 1979-04-22 to 1990-07-23 (last show, dying 7/26/90). Keyboard rig cross-checked against ryanstorm.substack.com 'The Grateful Dead Keyboard Rigs' (which traces the rig year by year) and the Wikipedia Brent Mydland article. Constant throughout: Hammond B3 organ + multiple Leslie speakers (commonly the 122/147 type with rotating horns). Primary keyboard chronology: 1979-81 Fender Rhodes Mark I (NOT a CP-70 yet) → 1982 Yamaha CP-70 (~one year) → 1983-86 Yamaha GS-1 (early FM synth, loaded sounds via punch cards) + analog synths (Minimoog, Sequential Circuits Prophet-5) → mid-80s E-mu Emulator II added → 1987-90 Kurzweil MIDIboard controller driving 2x Roland MKS-20 piano modules + Kurzweil 250RMX rack sampler + Roland S550 sampler + Oberheim Matrix 1000, processed through Lexicon PCM41/PCM70 + Akai MPX820 mixer (Bob Bralove programming/maintaining the MIDI system).
