Learning about the recording process and how it has changed over the years was pretty interesting. Listening to the differences in recording styles, like when Ella Fitzgerald would have to sing right into the microphone and actually have to sing over the instruments playing. As well as when Frank Sinatra would stand behind a wall so the feedback in his microphone. I also thought it was a little strange that MCA records has several studios in underground rooms that will produce certain sounds depending on how you wanted the song to come out. Also, finally learning how a record is made to produce sound, yet still being completely blown away at how it actually produces sound out of just a bunch of squiggly lines. I think sound is one of the craziest things, and how sound is just a bunch of created vibrations that vibrate our ear drum and that our brain can produce and decode music and sounds.
