This article zooms in on how American experimental composer David Rosenboom (b. 1947), a pioneer of brainwave music, employed the ARP 2500 and 2600 for his early 1970s neuromusical compositions. Beginning with a hippie-like trip for a promo of 2500, the relationship of Rosenboom and the ARP synthesizer traversed in something different than just interaction in music performance – the instrument became a part of the neurofeedback system created by young visioneer. Its follower, ARP 2600 would have the star moment featured in the Mike Douglas Show – being used for ‘plugged in’ John Lennon and Yoko Ono composing with their brains. Finally, the ARP synthesizers will travel with Rosneboom to York University in Toronto – becoming the point of attraction for students in one of the early academic electronic music Studios in canada.

Summer’70 Promo Tour with Gerald Shapiro

Rosenboom and the founder of the electronic music studio at Brown University met back in the time when David was a student at the University of Illinois Urbana-Champaign (1965-67) – then the center for experimental music in the US. Later the two met again at SUNY Buffalo where Rosenboom was a Creative Associate (1967-68). The circumstances brought them together together once more, in 1969 at the Audio Engineering Society convention in Los Angeles where Rosenboom presented a talk about his Neurona modules. At that time Gerald “Shep” Shapiro was a consultant for the ARP instruments. Somehow, that summer, Rosenboom ended up at Terry Riley’s house, learning with him playing tabla.

In the book of Eliott Schwartz [1], there’s a picture of Rosenboom sitting in front of the ARP synthesizer with a set of tabla. The image was made during the ’70 tour of Rosenboom and Shapiro – driving across the US in a van with ARP 2500 (both provided by the company). The friends did electronic music concerts in Washington, D.C., at George Washington University, in Nashville, and a couple of other places. On the way, they composed some electronic music pieces for ARP and other instruments – such as percussion or keyboard.
