I didn't even know where does that great riff originaly came from, shame on me.
17 minutes song... When music was not industrial yet.
Market now wants all songs whith same look, same taste, to sell them in the same 3 minutes boxes, like cans of soup in a supermarket.
I guess drugs helped them on this song.
I think Music itself is the best drug.
Zappa agreed whith that.
He was very severe with these musicians so that they do not take drugs.
