Electronic Music: Recorded Sounds

Sitting in music class and a sample of music is being played to us. Weirdest thing ever!!!!!!! The first piece is called Gesang der Junhlinge. Its by Karlheinz Stockhausen. I seriously do not know what was going on in this guys head as he is writing this. The song sounds like someone is getting abducted by aliens. No joke. There is a bunch oh whishes and whooshes. Plus, there is a part where it gets really really soft.......then BANG!!!! Really really soft........Bang!!!! Scared me. I cant forget to add the demonic children talking in the backround. A friend said they were getting poked with hot stick things and forced to do it. Most of the pieces follow but aren't as out of this world. That is except chance music. For example, John Cage. His piece is called 4' 33". It is silence. This John guy became famous because of silence. What he created was giving a time period and whatever happens in that time period happened was the music. Orchestra didnt play or any thing. Like if someone coughed they were part of it. It was the stupidest, almost five minutes of my life. Sat there in complete silence. If I was there i would have had so much fun. Started singing abnoxiously. Or something like that. I was waiting for someone to get the hiccups so all you would hear is HUP, HUP, HUP,. Would have been hillarious. The same friend as mentioned early said she wanted someone from the orchestra to start chewing gum. I wonder how pissed the ppeople who showed up to the first performance were. Probably sat there waiting for it to start. But that would have been the music. That would be pretty awesome actually, a bunch of angry people sitting there cussing and yelling. That cd would never leave my car. Or maybe they werent that smart. sitting there, waiting, than the conductor turns around and yells, "Thanks for coming out!!!" Can you say refund?
