I suspect without the background jazz these videos would appear even more tense than they already are. You'd hear the air conditioning kicking in, a dog barking in the background outside, a lawnmower. All while these two guys prattle on about trouser length, or the right way to fold a pocket square, or their thoughts on Japanese denim (hint: it's great!). The lack of music would only highlight the insanity of their mundane conversations. Like an existential horror movie.
