By the start of the 1980s, Jaco Pastorius had already changed the electric bass forever. His 1976 debut album redefined what the instrument could do, and his years with Weather Report — Heavy Weather, “Birdland”, the stadium tours — had made him arguably the most famous bass player in the world.
So what do you do next?
Jaco’s answer surprised almost everyone.
Rather than form another fusion group or chase commercial success, he assembled a modern big band featuring steel pans, harmonica, French horns and tuba, playing his own music at a time when large jazz orchestras had long fallen out of fashion.
He called it Word of Mouth. For a couple of extraordinary years, it became home to one of the most remarkable collections of musicians ever assembled on one stage.
The album that started it (1981)
The Word of Mouth story actually begins while Jaco was still in Weather Report. In 1980, he signed a solo deal with Warner Bros. and set about recording his second album — a project that shifted the spotlight away from his bass virtuosity and onto something he felt was undervalued: his writing and arranging.
Released in July 1981, Word of Mouth (the album) is a very different beast from his debut. There’s a bass-and-orchestra reimagining of Bach’s Chromatic Fantasy, a gorgeous big-band version of the Weather Report ballad “Three Views of a Secret”, the driving, steel-pan-flecked “Liberty City”, and a tender cover of The Beatles’ “Blackbird”. The guest list reads like a jazz hall of fame: Herbie Hancock, Wayne Shorter, Michael Brecker, Toots Thielemans, Hubert Laws, Jack DeJohnette, Peter Erskine.
Famously, if you bought one of the first copies, you wouldn’t have known any of that. A contractual dispute meant Columbia Records refused to allow its signed artists to be credited on a Warner release — so Jaco, in typical fashion, declared that if everyone couldn’t be listed, nobody would be. The first 50,000 LPs shipped with no musician credits at all.
From studio project to touring big band
Turning that studio creation into a real, touring band was the next step — and the way Jaco recruited for it says a lot about how he operated.
Take saxophonist Bob Mintzer. As Mintzer tells it, the two literally bumped into each other outside the toilets at New York’s Village Vanguard. Jaco looked at him and asked: “Who are you?” “I’m Bob Mintzer.” “Oh yeah… Mike Brecker told me about you. You want to be in my band?”
That was the audition. Mintzer went on to become one of the band’s key voices — as a soloist on tenor and soprano, and as an arranger — and stayed with Jaco for the next two years.
Much of the band came together the same way — through friendships, recommendations and the network of musicians Jaco had built over years on the road.
The core of the touring group included Randy Brecker on trumpet, Peter Erskine on drums, Don Alias on percussion, Toots Thielemans on harmonica, Othello Molineaux on steel pans, and a full complement of trombones, French horns and tuba — around 21 musicians at full strength.
Molineaux deserves a special mention. The Trinidad-born steel pan pioneer had been a close musical partner of Jaco’s since his Florida days, and it was his sound — steel pans woven through a modern big band — that gave Word of Mouth a texture no other ensemble in jazz had.
“There were no charts”
Here’s the part that surprised even the musicians involved.
You’d assume – after Weather Report – that it would be run on meticulous charts and endless rehearsals.
Bob Mintzer certainly expected that.
Instead, as he recalls:
“There were no charts… Hardly any rehearsing.”
The band would learn a couple of tunes, work out their own parts, and head straight to the gig.
It shouldn’t have worked.
Yet somehow it did.
One of the first great live documents: The Birthday Concert
One of the earliest recordings of the Word of Mouth band came on 1 December 1981 — Jaco’s 30th birthday.
To celebrate, he threw himself a birthday concert at Mr. Pip’s, a club in Fort Lauderdale, Florida, bringing the Word of Mouth band together for an ambitious performance of his latest music. The group was built around Florida’s Peter Graves Orchestra with Word of Mouth regulars flown in for the occasion — 14 horns, two steel pans and two percussionists, including Peter Erskine, Michael Brecker and Bob Mintzer.
The concert wasn’t released at the time. Instead, the tapes sat in the archives for more than a decade before finally appearing in 1995 as The Birthday Concert.
Today, many fans regard it as the finest live document of the early Word of Mouth band. Recorded before Jaco’s personal struggles became increasingly apparent, it captures the orchestra at its most confident, joyful and cohesive. The arrangements are expansive but never rigid, giving the musicians plenty of room to stretch out while still serving Jaco’s larger musical vision.
Highlights include the explosive “Soul Intro / The Chicken”, the lyrical “Three Views of a Secret”, and a sprawling 17-minute workout on “Invitation” — plus, of course, a big-band rendition of “Happy Birthday” itself. Just as importantly, the recording preserves the atmosphere of the band at its peak: a large ensemble playing with the spontaneity and flexibility of a much smaller group.
If you’re looking for the best place to hear what the Word of Mouth band was capable of in front of an audience, The Birthday Concert is arguably the ideal starting point.
On the road: 1982
1982 was the big band’s year. With Jaco now fully out of Weather Report, Word of Mouth became his main focus: a New York run, festival appearances including the Kool Jazz Festival (a complete radio recording of which was finally released in 2017 as Truth, Liberty & Soul on Resonance Records), an appearance at the Montreal International Jazz Festival, and — most famously — a September tour of Japan.
The Japan dates, recorded at the Budokan in Tokyo, Osaka Festival Hall and Yokohama Stadium as part of the Aurex Jazz Festival, captured the band at full power: Jaco originals like “Liberty City” and “Continuum” alongside Weather Report’s “Elegant People”, Ellington’s “Sophisticated Lady” (a stunning duet with Thielemans), and a “Reza / Giant Steps” medley that shows just how hard this band could swing.
By this point, signs that something was wrong were becoming increasingly difficult to ignore. Jaco’s behaviour grew increasingly erratic — at one point he threw his bass into Hiroshima Bay — and shortly after the band returned home, he was diagnosed with bipolar disorder. The brilliance on stage and the turbulence off it were happening at the same time, and the recordings from Japan are all the more poignant for it.
Untangling the albums: Twins, Invitation and Holiday for Pans
If you’ve ever tried to work out the Word of Mouth discography, you’re not alone — it’s genuinely confusing. Here’s the short version.
The Japan recordings were first released only in Japan, as two separate LPs: Twins I and Twins II (subtitled Aurex Jazz Festival ’82). For the rest of the world, Warner condensed the material onto a single album, Invitation, released in December 1983. The full set later appeared internationally as the two-disc Twins I & II – Live in Japan 1982, which is the version most streaming services carry today. Same band, same tour — three different packages.
There should have been another studio album, too. Jaco had completed work on Holiday for Pans, a project built around Molineaux’s steel pans, but Warner rejected the tapes and it was never officially released in his lifetime. Invitation went out instead, and it proved to be his final album for the label.
The Word of Mouth big band
The Word of Mouth big band, in its full form, lasted barely two years. It sold modestly, puzzled Warner Bros., and was enormously expensive to keep on the road. It never became the commercial success that many had hoped for.
Artistically, though, the story is very different.
At a time when fusion often leaned toward synthesizers and stadium-scale production, Jaco moved in another direction — toward acoustic brass, orchestral colour, Caribbean rhythms, and the arranging traditions of Duke Ellington and Gil Evans, all filtered through his own highly personal musical vision.
Musicians including Bob Mintzer, Peter Erskine, Randy Brecker and Othello Molineaux carried ideas from Word of Mouth into decades of work that followed, while the recordings themselves have steadily grown in stature.
The project also reveals another side of Jaco Pastorius: not simply the astonishing bassist, but a composer, arranger and bandleader with ambitions that reached far beyond the instrument that made him famous.
Listen to Word of Mouth, The Birthday Concert or Twins and you’ll hear music that remains ambitious, colourful and unlike anything else in jazz at the time.
The band itself existed for only a short period, but it stands as one of the most original and overlooked chapters of Jaco Pastorius’ career.
