(250-500 words) long, and should include specific observations, reactions, and questions you had while listening and watching. (What was interesting? surprising? confusing? appealing? etc.) It doesn't need to be an analysis or a "review," though of course you're welcome to include things you liked or didn't like about the music or the presentation. It needs to be obvious that you actually watched the whole thing, so be sure to include specific observations of/reactions to the music; if your report just says a lot of things like "I really liked how emotional all the pieces were!", I get suspicious and I'll probably ask you to rewrite it. I encourage you to do some googling to learn more about the music you're hearing.
