I have never gone back through Bear McCreary's blog, but this entry came up on my Google Alerts today even though the blog entry is from 2010.
This is completely amazing. I have enough music background to follow a lot of it, but a peek into the creative genius of Bear McCreary and how the music for the episode pulled together was a real treat.
This video is just a small portion of his blog entry which you can readHERE. The details of Chance's Fight/Dance Tango sequence with Agent Barnes are especially interesting!
