I need some help finding music that relates to "walls". By this I mean barriers or obstacles people build literally or figuratively. 

If you have any suggestions just post them here. 

If you have any video clip ideas relating to walls those would be useful too.

Compose a mashup in which you develop an interpretation of a film by creating a satirical trailer.

Mashups are developed by editing and rearranging scenes, and then adding music and voiceover to create a trailer or brief video. For this assignment, you will also need to develop a reading of the film so that you have an angle. Your mashup should deliver the same kinds of points that might come across in an argument about the meaning of the film/story, but it will likely do so with humor. (Although, it's possible to develop a serious trailer that expresses your interpretation.) If you believe a film is a testament to the randomness of fate, your voiceover should adapt the scenes in the trailer to deliver that message.

There are many samples of trailer mashups online--you'll have to adjust the expectations of these mashups to be more focused on a particular interpretation of the story.

You can also consider these examples:
