I know that burroughs recorded many albums himself but I think this was done by another group – it's psychedelic (very trippy..) music with william s burroughs reading lines from his poems. Basically… I've heard a few things that sound like what you're asking for but I'm not familiar enough with them to be sure. Maybe these links will help you narrow it down. You can hear clips on a couple of those sites and any list albums by others that he appeared on. I'm sorry if it's annoying to just get links that, for all I know, you might have already checked. I thought I could do better with this question but I ended up unsure. So, I hope it's better than nothing.
