This is Lachenmann's Gran Torso quartet available for download. The guy has also included the score. It's a genuinely amazing score, even if you don't read music it's worth looking at. I'm thinking of putting together a load of these sorts of scores that are aesthetically pleasing for a mate's amusement, may upload it here when I do so.
From
this blog which has a lot of similar stuff (music + score). Well worth a gander, plus Chrome's translator seems to not be doing too bad a job.
