Write discussion for the attached files

Write discussion for each attached file respectively, and each discussion is no less than 200 words.

This is your opportunity to guide the discussion. Posts can address some of the following:

What did you find most interesting in the lecture?

What, if anything, did you take issue with?

Are there relevant topics that you think deserve further exploration?

Feel free to comment on anything in the lecture you like: ask questions, challenge ideas presented, tell us what music/performances you liked or didn’t like, etc.

To be clear, each attached file should have a individual discussion towards the file, and each discussion should answer the questions above, so the total should be 4 discussions.
