This coincided with Professor [Amar] Bose mov- ing out of some space on the third floor of Building 26. He had stopped doing research at MIT at that point; he had been given what I think remains the only post of a full professor at MIT who teaches just one class and doesn’t do any research on campus. He moved out of his lab, and we promptly moved in because it had a nice acoustic treatment and was a much better environment for the new PDP-11. For the next twelve years, this was the area that the composers lived in. Lefford: What influenced your decision to build an all-digital experimental music studio? Did you draw from the experiences you had at other institutions? Vercoe: As a composer, I had no experiences in electronic music whatsoever in New Zealand where I did my undergraduate degrees.
