This was a difficult prompt and I've wracked my brains as to what to do. So I decided that "behind the scenes" is something that is not often seen or noticed but it's necessary to make something work. For the first time in about 30 years I lifted the flap of the cassette slot on my little hi-fi system and peered inside - I couldn't see a thing but with the flash I got a few cool photos. I don't own cassettes anymore and only a couple of cd's so this is definitely the inner workings of a real antique haha!
I agree with your definition of "behind the scenes," and I think you've done a great job with this image! (cassettes...yeah, true confessions: I even have a combo CD-cassette-radio system, which I still use for...the radio...and even CDs sometimes. It still works, so why not? lol
