It's well worth a listen. It contains a lot of his cut-up stuff, and also has the genius "Last Words Of Hassan I Sabbah". "Call Me Burroughs" is great - currently my copy is with a SY boardie here.
Oh yeah, have you seen the Burroughs films (the ones he made made with Anthony Balch in the 60's)? Totally amazing - "Towers Open Fire" and "The Cut Ups" are incredible. Have a look at them on
www.ubuweb.com, which streams them for free. I reckon you'd be well into them.
EDIT: Just checked Ubuweb, and they're still here:

EDIT 2: I met a fairly major "authority" on those films a few years back - he was there back in the day...a lovely bloke (Colin Davis be his name).
