in my class on saturday we were discussing this article about using bacteria to create different sounds on a cd. this lead to my students asking what is glitch? how do you describe glitch? one of the students had a basic idea about it, but most of the students had never heard of it. i don't really have much glitch in my music collection. but i'll probably bring in some mouse on mars next week for them to get an idea of what glitch sounds like.
