Apple II Part II: George Lewis in 1984

George LewisRainbow Family (Carrier, 2020; recorded 1984)

Three years ago, I wrote about a 1984 experiment in computer-driven improvisation. George Lewis, then researching at France’s IRCAM, presented a concert of top-notch improvisers — Douglas Ewart, Joelle Leandre, Derek Bailey, and Steve Lacy — performing with three networked Apple II computers that controlled Yamaha synths.

The concert is now available as an album on France’s Carrier label. It’s a valuable document of this early moment in the history of computer music. You have to excuse the limitations of computer sound at the time (try not to think of Tom Baker-era Doctor Who) but the computer element does work. Or, maybe it’s that the high-caliber musicians — Joëlle Léandre, Douglas Ewart, Derek Bailey, and Steve Lacy — are able to make it work.

The three Apple IIs don’t just bleep randomly. Lewis programmed them to take the (analog) musicians’ choices as input and make digital decisions to create output, including an option to add some randomness (i.e., to play freely). The source code Lewis used is lost, unfortunately, but his recollections of the strategies provide some useful insight in the CD liner notes. The programs did have a way to create a chunk of music from scratch, without inputs, and Lewis infers that this is how some of the pieces start.

Whether real or perceived, the computers manage to create some sublime moments of communication. Léandre’s duet includes a nice stretch where she’s calmly following the computers’ cues, but when she takes control, the machines respond with an anthemic burst.

Lewis had conceived of the three computers developing distinct personalities. What he found, though, was that the human musicians kept thinking of their bandmates as “The” computer. Same here, I have to admit. (See how I just called Léandre’s piece a “duet.”) It’s an interesting test of human perception.

Of course, the humans’ personalities and choices lead to specific characteristics for some of the pieces. Ewart produces a piece that is both forceful and calm, drifting like a Calder mobile and creating some of the most neatly matched improvising of the album. Bailey’s low-key piece features a stretch of harmonics that tease out some pleasant tone-tinkering from the computers.

The album culminates with a group session — all four humans, all three computers. It starts at a cautious pace, with the humans avoiding the “spew” factor that a group of this size can create. As the activity builds up, the computers seem to know to sometimes stay out of the way. Here’s a particularly noisy section with the humans taking the lead; the Apple IIs slip into the mix with small chimes and shimmers that get more assertive as the humans back down. It feels organic. Whether that’s excellent foresight on the part of Lewis the coder or just a lucky happenstance, we’ll never know — but Lewis’ knowledge and experience certainly increased the probability of these kind of moments.

You can sample and purchase the album on Bandcamp. I’m especially partial to Douglas Ewart’s piece.

George Lewis and the Apple II in 1984

takingthestageHere’s a nice slice of history. In the 1980s, IRCAM, the French institute for music, sound, and science, hosted a series of concerts called “Écoutez Votre Siècle,” and one of the installments was an early presentation of George Lewis‘ work with computer-generated sound.

A bit of that concert survives on the web, part of a 26-minute TV documentary that IRCAM produced. While we don’t get to hear the whole concert, the real treasure might be the interviews and rehearsal footage, which offer a look at the state of computer music in 1984.

Lewis’ piece, “Rainbow Family,” was created for a combination of human and computer players interacting. He assembled quite a team for it: Douglas Ewart (saxophone), Joëlle Léandre (bass), Steve Lacy (soprano sax), and Derek Bailey (guitar).

Lewis manned the computers and coordinated the rehearsals, during which the human players got acquainted with the tendencies of Lewis’ programs, much like feeling out another musician they’ve met for the first time.

I’ve known about Ewart but haven’t heard much of his playing; getting to know the man a little bit, while also hearing bits of his music, was enjoyable. He has some keen insights — noting, for example, that one strategy would be to consider the computer “an improviser who might not have the seasoning that we do.”

I’ve never heard Steve Lacy speak, something that didn’t occur to me until watching his video. His voice has an east-coast hip-cat lilt — which shouldn’t have been such a surprise, considering he comes from exactly that era.

Lewis himself is interviewed at length, mostly in French; he seems nearly fluent in the language. (Again, maybe I shouldn’t be so blown away. “Never mind that he’s a trombone great, an AACM biographer, and a computer-music pioneer — the dude speaks French!”)

Early in the show, Lewis switches to English to explain that his work is the barest glimmer of what artificial intelligence should eventually be capable of. He knew that his then-exciting technology was still a limiting factor; 1984 was a long way off from Tim Perkis’ real-time laptop musicianship. Still, the sounds Lewis wrests from the Apple II aren’t as dated as I was expecting. In the end, it does sound like the players found a rapport with the machines.

Interestingly, the documentary ends with the sound of trains — found sound, another type of sonic experimentation.

You can find the half-hour mini-documentary, along with others in the “Écoutez Votre Siècle” series, here.
