Wasteland: i have a video of the interview as well, as it was done over video chat, and i'm uploading it as we speak. So you may actually be able to see those expressions.
Regarding talking; most artists i've interviewed have been extremely easy to interview - they are so accustomed to the the process of interviewing that they basically just talk and talk trying to cover what they think you actually wanted to ask
Sometimes they predict what you're gonna ask within the first couple of words and you can see them be kinda waiting impatiently for you to finish the question so they can start their answer.
