Alternative alternative music

So spring of last year I got this album of alternative classical music. I'll link it here just so you don't have to go through the trouble of googling it. It's interesting...some of it is not so great but some of it is really interesting. 

A few weeks ago I was walking through the music department and I heard something that sounded like one of the pieces on the album and thought, "maybe it's by the same composer!"

Then I realized I was passing the practice rooms and that sound was in fact just a bunch of different people playing completely different things. Now I suspect I may have fallen for some sort of pretentious music prank that real musicians are playing on the world. But I think that about art sometimes too. 

Since then I've realized that this sound happens every day, and also there is an aspiring opera singer who never seems to leave this building.
