Magnetic Tape Manipulation

I listened to "Pendulum Music" by Steve Reich and though it's not the type of music I would usually listen to, I do consider it to be music. The definition given at the beginning of this year regarding music was an organized pattern of sound and silence. It sounded exactly like a heart beat on a terror movie track. I then listened to the radio to get a sample of what is considered "popular" today and from what I could tell, the majority of the garbage...I mean music....that is played is recorded using multi-tracking which essentially allows anyone with a computer to create a song that would most likely be considered popular. Multi-tracking allows for a lot of unique (not always good) sounds to be produced.
