I grade part time for the Labor Education dept at UIC. Staley is a new book published this past year by one of the professors, and is really an engaging story. Not only does it talk about the struggles the Staley workers faced, but also gives you a brief history of the company as well as some nuggets of labor history in general. I found myself very drawn into the story while reading the book, and was fortunate to go to a Q&A with the authors and a couple of the workers who were a part of that labor movement.
In a similar fashion, the documentary, Scratch, gives you an overview of how the DJ started hip hop music with some turntables. It is plenty enjoyable for those both familiar and newly initiated with the genre and lifestyle. A lot of rare interviews and performances from legends in hip hop including DJ Shadow, DJ Q-Bert, DJ Babu, and loads more. If you find a copy of either of these, I highly recommend checking it out.
