EEG in

[Andrew Schrock]

Look into work by Lucier... he has done pieces using highly amplified  
brain waves and orchestral ensemble. The drums for instance would make
some noise at least.. the timpani set was the most interesting, although I
think this sort of performance art / music is best left as inspirational
as a launch pad for other forms of music as opposed to being useful to
repeat. (if that makes sense) Basically the waves weren't useful for
control really.. they did change when he opened and closed his eyes. You
may of course be talking about something much more complex than I'm
thinking of. 

The reason he did the piece is that somebody on campus had access to the
equipment that they offered for use by musicians in the early 70's and he
was the only one who took them up on the offer :) 

He was at my University (Brandeis) for a while, now the music department
chair is Eric Chasalow. I saw a video of his "performance" at one point,
although I'm not quite sure where you would find one. It had a very
low-tech feel, in fact it might have been a unique copy since it was in
the library here.
