Listened to it thanks to an ogg upload (flacs were way too big in filesize). Interesting stuff. I liked the drum line - it has style. However, I did miss structure. In my opinion, not always does the monotone repetition is the way to go. Having a beat is already a little bit like structure, so you do have the beginnings of structure there. It was possible to introduce breaks and then put the beat back on - those breaks could have helped the composition evolve greatly.
Also, while drone music might basically be still for 70 minutes and not introduce anything new, in this case I did not feel that what I heard in the beginning was full-filling enough.

Still, it is an interesting piece of work. I wonder how much of it is unique and how much of it is copy-paste.

Cheers!
