Here's a quick overview of music/sound recording techniques that were state of the art in the 1980s. 

Begins with shots of a scenic English countryside, a cottage, and the area's surrounding green grass and trees. 

Inside the cottage, two violinists and a cellist play while a conductor wearing headphones conducts and a tape deck rolls, recording. 

CUs of tape moving through deck and VU meters. The hosts of the show, a black woman and a white man, arrive and listen to the musician. The female host listens to a music box, kneeling down and narrating.
